10 Days in Southeast Asia Under $2,000: A Real Budget With Real Numbers

The first time I tried to budget a Southeast Asia trip, I made the rookie mistake of pricing everything in dollars in my head and assuming I’d “figure it out there.” I came home from two weeks having spent almost exactly what I’d have spent in Europe — because I drank cocktails at rooftop bars, took Grab everywhere, and booked everything two days in advance.

This itinerary fixes that. It’s a real 10-day route I’ve run and refined: Bangkok → Chiang Mai → Siem Reap. Three countries-worth of variety (Thailand twice, Cambodia once), no exhausting daily transfers, and a total that lands comfortably under $2,000 per person including the long-haul flight if you book it right.

I’ll give you the day-by-day plan, actual numbers, the mistakes that quietly blow budgets, and the honest trade-offs — including the parts of each city that genuinely disappoint — so you can adjust it to your own travel style.

The route at a glance

Three stops, two short regional flights, ten nights. This keeps you out of the trap most first-timers fall into: trying to “see everything” and spending half the trip in transit.

Leg	Nights	Why it’s here
Bangkok	3	Gateway hub, cheapest flights, temples + street food
Chiang Mai	3	Slower pace, mountains, elephant sanctuaries, cheap
Siem Reap	4	Angkor Wat — worth a real chunk of time, not a day trip

You fly into Bangkok (BKK), out of Siem Reap (REP) or back through Bangkok. Book an open-jaw / multi-city ticket if your home airport allows it — flying in and out of the same city forces a wasteful backtrack.

What “under $2,000” actually includes

Let’s be precise, because most budget posts quietly exclude flights to make the number look good. This figure assumes:

• International airfare from a major US/EU hub: roughly $700–$950 round-trip if booked 2–4 months out (this is the swing factor — more below).
• Two intra-region flights, all lodging, all food, local transport, Angkor pass, and a reasonable buffer.
• Mid-budget comfort: private rooms in good guesthouses or 3-star hotels, the occasional nice meal, A/C when you want it.

If you’re a hostel-dorm backpacker, you’ll come in well under. If you want 4-star hotels and daily massages, you’ll go over. This is the sensible middle.

What to book before you leave

A handful of things should be locked in well before departure, not improvised on arrival. Apply for your Cambodia e-visa at the official site (evisa.gov.kh) at least a week out — it’s ~$36 all-in and takes a few business days. Book your cooking class in Bangkok early; the popular ones (Silom Thai Cooking School, May Kaidee’s) fill up in high season. Reserve your elephant sanctuary now — Elephant Nature Park routinely books out two to three weeks ahead, and the smaller ethical operators (Kerchor, BEES) have limited daily slots. Finally, buy travel insurance before you fly; SafetyWing and World Nomads both cover this kind of multi-country trip for roughly $40–60 for ten days, and you do not want to be uninsured on a scooter or in a Cambodian clinic.

The 10-day day-by-day itinerary (with costs)

All prices are per person, in USD, rounded to realistic real-world numbers. Couples save on lodging by splitting a room two ways — see the summary table for the solo adjustment.

Day 1 — Arrive Bangkok

You land jet-lagged. Don’t plan anything ambitious.

• Take the Airport Rail Link from Suvarnabhumi to Phaya Thai (~$1.30), then a Grab or taxi to your area. Don’t take the unmetered taxis touts offer at arrivals.
• Stay in Phra Nakhon (Old Town/near Khao San) for sightseeing, or Sukhumvit (around Asok/Thong Lo) for nightlife and the BTS Skytrain.
• Lodging pick: Arun Residence near Wat Pho runs ~$45/night and has genuine river views and a small rooftop — splurge-adjacent but unbeatable for location. On a tighter budget, Loftel 22 Hostel in Chinatown offers private rooms around $22.
• Honest negative: Old City accommodation can have serious noise issues — Khao San and its tributaries pump music well past midnight, and tuk-tuk horns start early. Ask for a room facing an interior courtyard, or stay a few blocks back toward the river.
• Dinner: street food on the corner. A plate of pad krapow with a fried egg is about $1.50–2.

Day 1 cost: lodging $25 + transport $5 + food $10 = ~$40

Day 2 — Bangkok temples and river

• Start early (8 am) before the heat. Grand Palace + Wat Phra Kaew (~$15 entry — the priciest single attraction of the trip, and worth it). Dress code is strict: shoulders and knees covered.
• Walk to Wat Pho ($3.50) for the reclining Buddha.
• Cross the river on the public ferry (~$0.15) to Wat Arun ($3).
• Evening: Chao Phraya Express boat down the river instead of an expensive dinner cruise.

Day 2 cost: lodging $25 + entries $22 + transport $3 + food $13 = ~$63

Day 3 — Markets and a cooking class

• If it’s a weekend, do Chatuchak Market in the morning. Otherwise, a Thai cooking class ($30–40) is one of the best-value experiences in the country — half a day, includes a market tour, lunch, and recipes. Book this before you leave home (see the checklist above); the good ones sell out.
• Late afternoon: rooftop drink if you want it ($10–15 a cocktail at the famous ones — or skip it and grab a local Chang beer for $2).

Day 3 cost: lodging $25 + cooking class $35 + food $8 + transport $4 = ~$72

Day 4 — Fly to Chiang Mai

• Book a morning AirAsia, Thai Lion Air, or Nok Air flight (BKK–CNX). Booked a few weeks out, this is $30–55 one-way. It takes ~75 minutes vs. an 11-hour overnight bus or train.
• Chiang Mai airport is 15 minutes from the Old City — a Grab is about $4.
• Lodging pick: Tamarind Village, a courtyard hotel inside the Old City walls, runs ~$70/night if you want a treat; for the budget version, The Common Hostel has clean private rooms around $20 with a garden café.
• Afternoon: wander the Old City walls and moat, visit Wat Chedi Luang. For dinner, head to the Chang Phueak (North Gate) night market and find Khao Soi Khun Yai — the legendary “cowboy hat lady” — just inside the gate. She typically sets up from late afternoon and sells out fast, so don’t show up at 8 pm expecting a bowl. It’s about $1.50 and it’s the best khao soi you’ll eat on this trip.

Day 4 cost: flight $45 + lodging $22 + transport $6 + food $10 = ~$83

Day 5 — Ethical elephant sanctuary

• This is a half- or full-day trip. Choose a genuine no-riding sanctuary — Elephant Nature Park is the well-known one, with smaller ethical options like Kerchor and BEES. Full-day tours run $50–80 including transport and lunch. Book ahead; these sell out weeks in advance.
• Avoid anywhere that offers elephant rides or circus-style shows. It’s both an ethics issue and a tourist-trap pricing issue.

Day 5 cost: sanctuary $70 + lodging $22 + food $6 = ~$98 (your most expensive Chiang Mai day — and one of the most memorable)

Day 6 — Doi Suthep and Sunday market

• Morning: ride a red songthaew up to Wat Phra That Doi Suthep (~$4 shared each way, ~$1 temple entry). The mountain temple has the best views over the city.
• Afternoon: relax, get a Thai massage ($6–10 for an hour — yes, really).
• Evening: if it’s Sunday, the Sunday Walking Street market on Ratchadamnoen Road is the best night market in northern Thailand.

Day 6 cost: lodging $22 + transport $9 + temple $1 + massage $9 + food $12 = ~$53

Day 7 — Fly Chiang Mai → Siem Reap

• There’s no direct budget flight on every day; you may connect through Bangkok. Plan for $90–140 for this leg and a half-day of travel. (Alternative: bus + border crossing is cheaper but eats a whole brutal day — I don’t recommend it on a 10-day trip.)
• Cambodia e-visa: you should already have this from the pre-trip checklist (evisa.gov.kh, ~$36). Do NOT use lookalike third-party sites that charge double.
• Lodging pick: Onederz Siem Reap has a rooftop pool and private rooms from ~$25; for a step up, Tanei Boutique Villa offers garden rooms and a pool around $50.
• Arrive Siem Reap, settle in. Pub Street is fun for exactly one evening — $0.50 draft beer is not a typo — but honest negative: it’s genuinely underwhelming after that first night. It’s loud, samey, and aggressively touristy. Spend later evenings on the quieter Kandal Village side streets instead.

Day 7 cost: flight $120 + lodging $25 + food $10 = ~$155 (the big-travel day)

Day 8 — Angkor: the big circuit

• Buy your Angkor Archaeological Park pass at the official ticket office: 1-day $37, 3-day $62, 7-day $72. Get the 3-day — Angkor is enormous and one day is a mistake (more below).
• Hire a tuk-tuk driver for the day (~$18–25 for the small circuit, more for the grand circuit). A good driver becomes your guide and waits for you.
• Sunrise at Angkor Wat (be there by 5 am), then Bayon (the face temples) and Ta Prohm (the “Tomb Raider” tree temple).
• Honest negative: the famous sunrise at Angkor Wat now draws hundreds of people jostling at the reflecting pool. It’s still worth doing once, but temper expectations — the quieter sunrises at Pre Rup or Srah Srang are arguably more peaceful.

Day 8 cost: Angkor 3-day pass $62 + tuk-tuk $22 + lodging $25 + food $12 + water/snacks $4 = ~$125

Day 9 — Angkor: outer temples + Tonlé Sap

• Use day 2 of your pass for the grand circuit or a trip out to Banteay Srei (the pink sandstone carvings, ~37 km out).
• Late afternoon: a boat trip to the Tonlé Sap floating villages — go with a reputable operator, around $15–20. Be aware the heavily marketed Chong Khneas village can feel like a staged tourist run; ask your guesthouse for the less-commercialized Kampong Phluk option.

Day 9 cost: tuk-tuk $25 + boat $18 + lodging $25 + food $12 = ~$80 (pass already paid)

Day 10 — Slow morning, depart

• One more sunrise or a lazy breakfast and pool morning. Most Siem Reap guesthouses have a pool — use it.
• Depart from Siem Reap–Angkor International Airport (SAI) — note it’s about 40 minutes / 50 km from the city, so leave extra time and budget ~$15 for transport.

Day 10 cost: lodging (or checkout) + transport $15 + food $10 = ~$25

Adding it up

Category	Per-person cost
International flights	$700–950
2 regional flights	~$165
Accommodation (9 nights)	~$215
Food	~$110
Local transport	~$70
Attractions + tours	~$280
Cambodia visa	~$36
Buffer / misc	~$150
Total (couple, sharing rooms)	~$1,726–1,976
Solo adjustment (add ~$20/night × 9 nights)	+~$180

You land under $2,000 with room to breathe — and that’s with a decent international fare. Traveling solo, expect closer to $1,900–2,150 once you cover a private room alone each night; if that pushes you over, hostel dorms or a few nights of a more basic guesthouse will pull you comfortably back under.

Common mistakes that quietly blow the budget

1. Booking the international flight late. This is the single biggest variable. The difference between booking 3 months out and 2 weeks out can be $400+. Set fare alerts the moment you commit to dates.

2. Buying the 1-day Angkor pass. People think they’ll “do Angkor in a day.” You can, but you’ll be hot, rushed, and templed-out by 11 am. The 3-day pass is only $25 more and lets you go at sunrise, escape the midday heat, and return. It’s the best-value upgrade on the whole trip.

3. Using the airport money changers and ATMs that charge fat fees. Cambodia runs largely on US dollars — bring clean, untorn small bills. In Thailand, SuperRich exchange booths give far better rates than airport counters. ATMs in both countries often charge a per-withdrawal fee (~$5–7), so withdraw larger amounts less often.

4. Over-Grabbing. Grab is convenient but it adds up. In Chiang Mai’s Old City, you can walk almost everywhere. In Bangkok, the BTS Skytrain and MRT are faster than a car stuck in traffic anyway.

5. Falling for the “the temple is closed today, let me take you to a special shop” tuk-tuk scam in Bangkok. The Grand Palace is open. Anyone telling you otherwise wants a commission.

6. Booking the Cambodia visa on the wrong website. Search results are littered with third-party sites charging $50–80 for a $30 visa. Use the official evisa.gov.kh only.

Insider tips a first-timer wouldn’t know

• Eat where the locals queue, not where the menu has photos. Photo menus and English-first signage usually mean tourist pricing. The best pad krapow I had cost $1.50 from a cart with no English at all.
• Carry small bills. Vendors and tuk-tuks often “can’t make change” for a 1,000-baht note — sometimes genuinely, sometimes conveniently.
• Sort your SIM/data the moment you land. In Thailand, grab an AIS or DTAC tourist SIM at the airport — a 15-day, 15–30 GB package runs about $8–15. In Cambodia, Metfone or Smart SIMs are cheap and widely available; expect roughly $5–8 for a generous data bundle. An Airalo eSIM works too if your phone supports it (~$10–17 for a regional plan), but a physical local SIM is usually cheaper and includes a local number for tuk-tuk and guesthouse calls.
• Hydrate and pace temple days. Southeast Asia heat is no joke at midday. Locals nap or stay indoors from noon to 3 pm for a reason — structure your sightseeing around early mornings.
• Tip your tuk-tuk and sanctuary guides. It’s not strictly expected everywhere, but a few dollars goes a long way and these folks are genuinely working hard for you.

Honest trade-offs

Do the regional flights if you value your time — they turn 11-hour overnight slogs into 90-minute hops for not much money. But take the overnight train Bangkok → Chiang Mai if you want the experience and want to save a hotel night; the second-class sleeper is comfortable, scenic at dawn, and a story in itself.

Stay in Sukhumvit, Bangkok if you want nightlife and Skytrain access. Stay in the Old Town if temples and atmosphere are your priority and you don’t mind relying on boats, Grab, and a little late-night noise.

Go in the dry season (Nov–Feb) for the best weather — but expect higher prices and crowds at Angkor. Travel in May–June (shoulder, hotter, occasional rain) and you’ll have cheaper rooms and quieter temples. I genuinely prefer the green, near-empty Angkor of low season, but bring a rain layer.

Spend more time in Siem Reap, less in Bangkok if you came for history and culture. Flip it if you came for food, shopping, and energy.

Your actionable next steps

This itinerary only works if you front-load a few decisions. Do these four things this week:

1. Set a multi-city fare alert now. Open a flight-tracking tool and create an alert for your home airport to BKK (in) and REP (out) as an open-jaw search, for dates 2–4 months ahead. That single fare is the foundation the entire under-$2,000 budget rests on — lock in a good one and the rest falls into place almost exactly as priced above.

2. Apply for the Cambodia e-visa at evisa.gov.kh as soon as your dates are firm. It’s quick, it’s ~$36, and getting it out of the way removes the single most common border-crossing headache. Ignore the lookalike sites.

3. Book your Bangkok cooking class and Chiang Mai elephant sanctuary early. The best of both — and Elephant Nature Park in particular — routinely book out two to three weeks ahead. These are the experiences people remember most from the trip, so don’t leave them to chance.

4. Buy travel insurance before you fly. A ten-day policy runs about $40–60 and covers the scooter spills, missed connections, and clinic visits that a budget itinerary has no slack for.

Do those four things and you’ve turned a wishlist into a real, costed, bookable trip — one that genuinely lands under $2,000, with the temples, the khao soi, and the elephants all waiting on the other end.
