It’s December 3rd. You’ve got nine days off over the holidays, a vague plan to visit family in Lisbon and “maybe see Porto,” and a browser with 31 tabs open — three flight comparison sites, two Airbnb searches, a Reddit thread about December weather in Portugal, and a Google Doc titled “TRIP PLAN” that contains exactly one line: figure out trains.
Sound familiar? The problem isn’t that you’re disorganized. It’s that you’re starting from a blank page, and a blank page is the worst possible starting point for a holiday trip — when prices spike, daylight is short, and half the museums close on the 25th.
This holiday travel itinerary planner fixes that. It’s a fill-in-the-blank system, not a generic template. You answer a fixed sequence of questions in order, each one closing off the chaos a little more, and in about 30 minutes you have a skeleton itinerary you can actually book against. I’ve used some version of this for years of holiday trips — Christmas markets in Central Europe, a New Year’s run through northern Italy, family-and-recovery splits in the Algarve — and it works because it forces decisions in the right order.
Let’s build yours.
Why holiday trips break generic templates
A normal itinerary template assumes flexible dates, normal opening hours, and average prices. Holiday trips violate all three:
- Dates are rigid. You’re working around fixed days off, family obligations, and other people’s calendars.
- Hours are weird. Dec 24, 25, 26, Jan 1 — many attractions, shops, and even some restaurants close or run half-days. Public transit drops to Sunday schedules or stops entirely.
- Prices are non-linear. A flight that’s €90 on December 10th can be €340 on December 23rd. Hotels in market-city centers (Vienna, Strasbourg, Prague) sell out weeks ahead.
- Daylight is short. In Northern Europe in late December you get roughly 8 hours of usable light. Your “full day of sightseeing” is really 5–6 hours.
A blank spreadsheet doesn’t know any of this. The system below bakes it in.
The 30-minute system: six blanks, in order
Set a timer. Don’t research yet — just fill blanks with your best current answer. You’ll refine later. The order matters: each blank constrains the next so you stop spinning.
Blank 1 — The Fixed Points (5 min)
Write down everything that is non-negotiable before you touch a single destination idea.
My fixed points:
– Arrive home country airport by: _
– Hard commitments (family dinner, NYE plans, return-to-work): _
– Total nights available: _
– Travelers + constraints (toddler nap, in-law mobility, dog): _
– Total budget ceiling (all-in): ____
This is the single most-skipped step and the most important. If your mother-in-law’s lunch is locked for the 25th in Lisbon, your “side trip to Porto” can only be the 27th–29th. The fixed points draw the box you get to play in.
Worked example: 9 nights, Dec 22–31. Fixed: family lunch in Lisbon Dec 25, must be back at work Jan 2. Two adults, no kids. Budget ceiling €2,200 all-in from London.
Blank 2 — The Anchor City (3 min)
Every holiday trip has one. It’s where the obligation or the main reason lives.
Anchor city: _
Nights I’ll spend here: _
Don’t overthink. In our example the anchor is Lisbon — that’s where family is. Decide a realistic number of nights at the anchor before you add anything else. Holiday trips fail when people bolt on three extra cities and end up spending the actual holiday in transit.
Our call: 5 nights Lisbon (Dec 22–27), built around the Dec 25 lunch.
Blank 3 — The One Side Trip (4 min)
The discipline here: one side trip, not three. A holiday trip with two bases is relaxing. A holiday trip with four is a logistics job you assigned yourself.
Side trip candidate: _
Travel time from anchor: _
Nights there: _
Is it open over the holiday? (rough check): _
For Lisbon, the obvious move is Porto (about 2h45–3h by Alfa Pendular train, roughly €30–45 booked ahead). We’ll do 3 nights: Dec 27–30, back to Lisbon late on the 30th, fly home Dec 31.
If your anchor were Vienna, the one side trip might be Salzburg (2h30 by railjet). If it’s Tokyo, it’s Kyoto (2h15 by Shinkansen). Pick the high-payoff, low-friction one and stop.
Blank 4 — The Daylight Budget (5 min)
This is the insider step. For each destination, write the actual usable daylight, then plan one major thing + one minor thing per day — no more.
City: _
Sunrise / sunset: _
Usable hours: _
Closed days to avoid: _
In Lisbon in late December, sunrise is around 7:50am, sunset around 5:25pm — better than Northern Europe, but still under 10 hours, and the low winter sun fades early. Crucially: major Lisbon sights and most shops close on Dec 25, and many run reduced hours on the 24th and Jan 1.
So your Dec 25 in Lisbon is a family day by design, not a wasted sightseeing day. The system surfaces that instead of letting you plan a museum that’s shut.
Blank 5 — The Skeleton (6 min)
Now drop your fixed points, anchor nights, side trip, and closures into a day-by-day grid. One line per day. Don’t fill in restaurants or opening times yet — just the shape.
Format: Day / Date — City — Major thing — Note (transit / closed / commitment)
Start by filling just the rows you already know from Blanks 1–3 — the fixed commitment, the transit days, the closures — and leave the rest blank. It should look something like this before you complete it:
Date City Major thing Note Dec 22 London → Lisbon arrival transit; evening Dec 23 Lisbon ____ Dec 24 Lisbon ____ sights close early Dec 25 Lisbon Family lunch most things closed — fixed Dec 26 Lisbon ____ Dec 27 Lisbon → Porto ____ transit (½ day) … … … …
Once the fixed cells are locked, the empty ones almost fill themselves — you’re now choosing activities inside a box, not staring at nine open days. We’ll do the full version in the next section.
Blank 6 — The Booking Triggers (4 min)
Holiday trips have a hierarchy of what sells out and spikes first. Write your booking order:
- Flights (book first — these move the most and fastest near the holidays)
- Anchor accommodation (center-city holiday stays sell out)
- Long-haul intercity transport (reserved-seat trains like Alfa Pendular, Shinkansen, railjet)
- Any single timed attraction you must do (NYE dinner, a specific tour)
- Everything else — book later or improvise
My booking order + deadlines: ____
Set calendar reminders. “Book Lisbon–Porto train by Dec 10” beats “book trains” every time.
One operational detail that belongs in your booking order: Alfa Pendular and Intercidades tickets open exactly 30 days before departure on CP’s site (cp.pt). For a Dec 27 Lisbon–Porto departure, that means the cheapest Promo fares appear around Nov 27 — set the reminder for that morning, not “sometime in December.” This is also the blank where you decide your luggage strategy: keep your Lisbon anchor accommodation through the Porto leg (if the math works) so you can leave the bulk of your bags at the anchor base and travel to Porto with a single carry-on. Dragging full suitcases through a December station is misery you can design out before you book.
60-second sanity check
Before you leave the skeleton, run these three yes/no questions. Any “wrong” answer means you go back one blank — not forward.
- Does any transit day land on Dec 24, 25, or 31? If yes, confirm the train/flight actually runs that day and isn’t on a holiday timetable. (Reduced or no service on the 25th and Jan 1 is common.)
- Is the side trip under ~3 hours each way? If no, it’s a second trip, not a side trip — cut it or extend the nights so the transit earns its keep.
- Did you price the return leg first? If no, stop and do it now — the return day frequently determines the whole shape (see Mistake #1).
Three yeses and your skeleton is structurally sound. Now flesh it out.
The fully worked itinerary (copy this)
Here’s the Lisbon + Porto example fully built out — real timings, realistic costs, holiday closures handled. Two adults, from London, Dec 22–31.
| Date | City | Major thing | Minor / note | Rough cost |
|---|---|---|---|---|
| Dec 22 | London → Lisbon | Evening arrival, settle in | Flight ~2h40; check in, dinner in Alfama | Flight €130 pp |
| Dec 23 | Lisbon | Alfama + São Jorge Castle | Tram 28 early to beat crowds | €15 entry |
| Dec 24 | Lisbon | Belém (Jerónimos, pastéis) | Sights close ~1–2pm; afternoon free, Consoada dinner | €12 + €5 |
| Dec 25 | Lisbon | Family lunch (fixed) | Almost everything closed; walk Eduardo VII park | €0 |
| Dec 26 | Lisbon | LX Factory + Time Out Market | Sintra is doable but cold/short days — optional | €0–25 |
| Dec 27 | Lisbon → Porto | Morning Alfa Pendular ~9am | Arrive ~11:45; afternoon Ribeira riverfront | Train €38 pp |
| Dec 28 | Porto | Niepoort cellar in Gaia + Dom Luís bridge | Smaller cellar that takes walk-ins; cross the bridge upper deck at dusk | €25 |
| Dec 29 | Porto | Livraria Lello + Clérigos + Mercado Bom Sucesso | Lello timed ticket at opening; Bom Sucesso for lunch (see note) | €12 |
| Dec 30 | Porto → Lisbon | Late afternoon train back | Buy ahead; arrive evening | Train €38 pp |
| Dec 31 | Lisbon → London | Morning flight home | NYE-eve flights cheaper than NYE-day | Flight €120 pp |
Two non-obvious Porto picks. Skip the much-Instagrammed (and December-crowded) Mercado do Bolhão in favor of Mercado Bom Sucesso — a covered food hall a short walk from the center that’s quieter on a December morning, fully indoor, and an easy lunch when the weather turns. For port, the big Gaia houses (Sandeman, Graham’s) run rigid timed tours; Niepoort and a few smaller lodges still take walk-ins for a tasting, which fits a flexible holiday afternoon far better than a 90-minute group slot.
Rain anchors. Weather in late December is a coin flip. If Lisbon pours, default to the Calouste Gulbenkian Museum (a calm, fully indoor half-day). If Porto pours, default to Livraria Lello plus the covered Mercado Bom Sucesso — both indoors and close together. Each city now has a downpour that doesn’t blow up the plan.
Rough all-in for two:
- Flights: ~€500 (2 × €250 round-trip-ish split)
- Trains: ~€152 (4 × €38)
- Accommodation: 8 nights ≈ €900 (mix of mid-range central stays)
- Food/drink: ~€480 (€30 pp/day, lower on family days)
- Attractions/misc: ~€160
Total ≈ €2,190 — just under the €2,200 ceiling. If you’re over, the first lever is accommodation (drop one Porto night and add it to Lisbon, or go a tier down), not flights.
Notice what the system did: it put the closed day (Dec 25) on the fixed commitment, kept Porto to a clean 3-night block, and respected short winter days by scheduling one anchor activity per day.
Common mistakes (the non-obvious ones)
1. Booking the outbound flight before checking the return day’s prices.
Holiday return flights on Jan 1–2 are often the most expensive leg of the whole trip. Price the return first — it frequently determines whether you come home on the 31st (cheaper) or the 2nd (pricier), which reshapes your entire skeleton.
2. Planning a sightseeing day on Dec 25 or Dec 26.
Even in cities that “stay open,” hours are gutted. Always pre-assign these days to family, rest, a long walk, or a meal you’ve booked. Don’t let a closed Jerónimos Monastery ruin your morning.
3. Underestimating transit days as “free” days.
A 9am train to Porto eats your morning; you arrive, find the apartment, and it’s lunch. That’s a half-day, not a full one. Count travel days as 0.5 sightseeing days in your daylight budget.
4. Ignoring reduced public transport schedules.
On Dec 25 and Jan 1, metros and buses often run Sunday/holiday timetables or stop early. If your plan depends on the last metro home from a NYE viewpoint, check before you commit — many cities run special NYE service, but not all.
5. Centering the trip on one famous restaurant you didn’t book.
The places worth building a day around are full by mid-December for holiday week. Either reserve the moment your dates are locked, or design around walk-in-friendly spots (markets, tascas, izakayas) and stop pretending.
6. Same-day connections with no buffer in winter.
A tight train-to-flight on Dec 31 with fog or holiday delays is a gamble. Leave a buffer or sleep near the airport.
Insider tips that signal you’ve done this
- Search flexible dates by week, not by day, two months out. For a December trip, the cheapest departure is often two or three days earlier than you assumed, and the early arrival gives you a low-pressure settling-in day instead of a frantic one.
- Book reserved-seat intercity trains the day they open. Alfa Pendular, railjet, Shinkansen, and TGV holiday seats sell at the cheapest tier first. The €30 Lisbon–Porto fare becomes €45+ as it fills, and CP opens the booking window exactly 30 days out (see Blank 6).
- Screenshot opening hours, don’t bookmark them. Holiday hours change and pages get updated; a screenshot with the date is your evidence and works offline.
- Add the holiday closures to your phone calendar as all-day events. “Dec 25 — most sights closed” appearing on the day is a better safeguard than a buried note.
Honest trade-offs
One base vs. two. Do a single base if your trip is 4 nights or under, or if you’re traveling with a toddler or anyone with mobility limits — packing and re-settling is the most exhausting part of any trip, and short winter days make travel mornings feel longer. Do two bases only when the side trip genuinely earns 2+ nights and the transit is under ~3 hours.
Book everything now vs. leave room to improvise. Lock flights, anchor accommodation, and long trains early — these punish you for waiting. But resist over-booking daily attractions in advance for a holiday trip; weather and family timing shift, and a fully pre-paid day removes the flexibility that makes holidays pleasant. Reserve the few irreplaceable things; improvise the rest.
Stay central vs. stay cheaper. In December, central accommodation in a walkable old town is worth the premium — short days and cold weather make long transit to a budget suburb stay feel much worse than it does in July. If budget forces a choice, cut a night, not the location.
Famous side trip vs. slower anchor. If your anchor city is somewhere you’ll rarely return to, consider skipping the side trip entirely and going deep — more neighborhoods, repeat visits to favorite spots, actual rest. The “must add Porto” instinct is sometimes FOMO dressed up as planning. The honest test is the one from your sanity check: does the side trip clear 2+ nights and under-3-hour transit and leave the anchor with enough breathing room? If you’re stretching on any of those, the slower anchor is usually the better holiday — you came back rested instead of having “covered” two cities you barely felt.
Your actionable takeaway
Open a blank doc right now and paste in the six blank headings — Fixed Points, Anchor City, One Side Trip, Daylight Budget, Skeleton, Booking Triggers — then set a 30-minute timer and fill them in order, worst-guess answers allowed. Run the 60-second sanity check at the end. When the timer ends, you won’t have a perfect trip, but you’ll have a bookable skeleton, your closure days handled, and a clear booking order with deadlines.
Then do exactly one thing today: price your return flight. That single number anchors everything else — and it’s the one that gets more expensive while you keep that doc titled “TRIP PLAN” sitting empty.
