How to plan a holiday, step by step

Planning a trip can feel like a hundred little decisions all at once. It's much calmer when you take them in order. Here's the sequence we'd follow for almost any holiday — with the tools and the common mistakes flagged along the way.

Step 1 — Set a realistic budget first

It's tempting to pick a destination and work out the cost later, but that's how trips quietly balloon. Decide what you can comfortably spend, then shape the holiday to fit. Think in terms of the whole package, not just the flight: accommodation, food and drink, activities, local transport, insurance, and a buffer for the unexpected.

Our trip budget calculator gives you an all-in figure in seconds, including the bits people overlook — airport parking, baggage fees, travel money costs and tourist taxes. Knowing your number up front makes every later decision easier.

Step 2 — Choose your dates and destination together

Dates and destination influence each other through price and weather. The same place can cost wildly different amounts depending on whether you travel in peak season, shoulder season or off-peak. If your dates are flexible, you'll almost always find better value — and quieter sights.

• Match the season to what you want: sunshine, snow, festivals or low crowds.
• Weigh travel time against trip length — a long-haul flight for a four-night break can eat the holiday.
• Be flexible where you can. Mid-week departures and shoulder-season dates tend to be cheaper.

Step 3 — Book in the right order

Once you've settled the where and when, book in a sequence that protects you and keeps options open:

1. Flights and accommodation first — they anchor everything and move most in price.
2. Airport transfers and car hire next, before the cheaper options sell out.
3. Key activities and restaurants that need booking ahead.
4. Everything else — you can leave the flexible bits until closer to the time.

Step 4 — Sort the essentials early

These are the jobs that cause real stress when left late, because some have lead times measured in weeks:

• Passports: check the expiry date now. Many countries require at least six months' validity beyond your travel dates.
• Visas and entry rules: confirm whether you need a visa or travel authorisation, and apply in good time.
• Travel insurance: buy it as soon as you book, not at the airport — cancellation cover then protects you from day one.
• Health: check whether any vaccinations are recommended, and pack enough of any prescription medication in your hand luggage.
• Travel money: compare cards and rates, and avoid paying in your home currency abroad, which usually costs more.

Set your departure date in the holiday countdown and it lays these out week by week, ticking off the ones you've already passed.

Step 5 — Pack and prepare

In the final stretch, the goal is simply to arrive relaxed and ready. Build a list rather than packing from memory — the packing-list generator tailors one to your trip type and length, including the essentials people always forget. Then handle the last-week admin:

• Check in online as soon as it opens and save your boarding passes.
• Download offline maps and any travel or airline apps you'll need.
• Confirm your first-night accommodation and how you'll get there.
• Tell your bank you're travelling, and check your data roaming or eSIM.
• Leave a copy of your itinerary with someone at home.
