How to Plan a Long Trip: A Simple System That Works

What do I decide first when planning a long trip?

Most overwhelm comes from choosing a route before the constraints are known. Every route question (how many countries, how fast, how comfortable) is answered by three numbers: trip length, total budget and season. Settle those first and the route mostly shrinks to a few sensible options.

Season matters because it can rule out whole regions. Monsoon rain, cyclone months, extreme heat, mountain passes closed by snow and peak-price holidays all change what a place is worth. Pick the order of regions so you are in each one during its good months.

1. Set trip length in weeks, including a few buffer days at both ends.
2. Set a total budget: daily spend multiplied by days, plus pre-trip costs, plus contingency.
3. Note season constraints for each candidate region (rainy season, cold, festivals, school holidays).
4. Sketch a rough route as a list of regions in order, with entry and exit cities. No dates yet.
5. Check visa, passport and onward-travel rules for each country on that list.
6. Book only the anchors (see the table below), then stop.

How much should I plan in advance? The 70/30 rule

A workable rule of thumb is to fix roughly 70% of the skeleton and leave 30% flexible. The skeleton is the entry and exit points, the key regions, and anything tied to a season or a date. Individual days, activities and most mid-trip beds stay open.

Pace is the other half. Aim for a minimum of 3-5 nights per base and avoid one-night stops. Each move costs a half to a full day in packing, transit, check-in and re-orienting, so a one-night stop buys you a bed and loses a day.

Use a north-to-south Vietnam route as a worked example: Hanoi, Ninh Binh, Hue, Hoi An, Da Lat, Ho Chi Minh City. Internal moves are cheap and easy to book a day or two ahead (sleeper trains, buses, domestic flights), so there is little reason to lock them months early.

What is the best way to organize a long trip: spreadsheet or app?

Use one tool. Scattered notes, screenshots, email searches and three apps are what make planning feel impossible. A single Google Sheet or one Notion database works equally well; the rule is one source of truth, with links rather than duplicated information.

Store each booking confirmation once in cloud storage and paste the link into the sheet. If a date changes, you edit one cell, not four documents.

TAB 1  Route      | Order | Place | Arrive | Leave | Nights | Status (idea/booked) | Next move
TAB 2  Bookings   | Type | Provider | Dates | Ref no. | Cost | Currency | Cancel-by | Link
TAB 3  Budget     | Country | Days | Daily budget | Planned | Actual | Difference
TAB 4  Documents  | Passport expiry | Visa type | Entry date | Days allowed | Last legal day | Insurance policy no. | Link
TAB 5  To-do      | Task | Deadline | Done?

How do I build a budget for months of travel?

Set a daily budget per country, because costs vary enormously between, say, Vietnam and Japan. Split it into categories, then add a 10-20% contingency on the total. Use the higher end for a first long trip, since slow days, illness, a missed connection or a rebooked flight are normal events, not exceptions.

Illustrative example for a 60-day trip at a planned 40 per day in a low-cost region (swap in your own currency and numbers):

Which pre-trip costs do people forget?

The on-the-road budget is only part of the cost. Add these before you decide the trip is affordable: flights in and out, travel insurance, visas, vaccines and travel-clinic visits, gear (pack, shoes, rain layer, adapters), a phone plan or eSIM, and any rent or storage you keep paying at home.

Also keep an emergency fund for a flight home. A last-minute one-way ticket can cost far more than a planned one, and the fund should sit separately from the daily budget so you never spend it by accident. Budget for slow days too: rest days, bad weather and illness all cost a bed and food with no activity.

How do I manage money and currencies for months abroad?

The aim is to avoid fees at every layer: card, ATM, conversion and exchange. Set this up before leaving, because ordering cards abroad is slow and unreliable.

1. Carry two debit or credit cards with no foreign transaction fees, on different networks if possible (for example one Visa and one Mastercard).
2. Add a third backup card and keep it separate from your wallet, such as in your main bag, never together with the other two.
3. Open a multi-currency account such as Wise or Revolut. Hold or convert money in advance and use its card for spending and withdrawals. Compare current fees and free-withdrawal limits first.
4. Withdraw larger amounts less often. Many ATMs charge a flat fee per withdrawal, so one big withdrawal beats several small ones. Carry only a day or two of cash and leave the rest locked away.
5. When a card terminal or ATM offers to charge you in your home currency, decline and pay in local currency. The offered rate (dynamic currency conversion) usually includes a poor markup.
6. Avoid airport exchange counters. Withdraw a small amount from an ATM on arrival, or arrive with a little cash for the first transport.
7. Tell your bank your travel plans or enable travel notices in its app, and keep its international phone number saved offline.

What should I track, prepare and avoid regretting?

Track different things before leaving and on the road. Before leaving, the priority is documents and bookings. On the road, it is deadlines and cash. Confirm current visa, passport and entry rules for every country on your route with each government's official immigration site; they change and the details differ by passport.

Passports usually need to be valid for about six months beyond your entry date, and some countries require blank pages and proof of onward travel. Choose travel insurance that explicitly covers long trips and the activities you plan (motorbike riding, trekking and diving are often excluded or need add-ons).

1. Download offline maps for each region in Google Maps and Maps.me before you leave wifi.
2. Set up an eSIM before arrival, or plan to buy a local SIM at the airport or a shop in town.
3. Save passport, visa, insurance and booking copies in cloud storage, plus an offline copy on your phone and one printed or emailed to a trusted contact.
4. Log spending daily in Trail Wallet, a phone note or your sheet, in one default currency so countries compare cleanly. Use Splitwise for shared costs, and review actuals weekly rather than agonizing over each purchase.
5. Pack light: a rule of thumb is to lay everything out, then remove a third. Overpacking is among the most-cited regrets, along with rushing and having no document backups.
