The flight from London to Rome was £320 in June. In November, the same flight was £120. That's a 63% difference. The hotel that cost €250 a night in July cost €110 in October. That's a 56% difference. The restaurant that had a two-hour wait in August had empty tables in May. The difference? Timing.
A reader named Tom emailed me last year. He had booked a trip to Italy for August. He paid £800 for flights for his family of four. He paid €300 a night for a hotel near the Colosseum. He paid €30 per person for a Vatican tour. He complained that Italy was expensive. I asked him when he went. August. I asked him where he stayed. Tourist centre. I asked him if he'd considered September. He hadn't.
The Travel Budget Calculator has a "season" toggle. Most people ignore it.
I ran Tom's trip through the calculator for August and for September. August total: £3,200 for 7 nights (flights, hotel, food, activities). September total: £2,100. He could have saved £1,100 by shifting his trip by three weeks. He was annoyed at himself. He said "I didn't know the difference was that big."
The Trip Cost Estimator can help you compare seasons side by side.
Let me break down the real cost differences by season for popular destinations, based on data from the estimator and from real travellers.
Italy (Rome, Florence, Venice)
Peak season (June-August): Hotels €150-250 per night. Flights from London £250-350. Restaurant meal €20-30. Museum tickets €15-25. Crowds are massive. Lines are long.
Shoulder season (April-May, September-October): Hotels €80-150 per night. Flights from London £100-180. Restaurant meal €15-20. Museum tickets same price, but no queues. Weather is still good (18-25°C). Crowds are moderate.
Low season (November-March, excluding Christmas): Hotels €50-100 per night. Flights £50-120. Some attractions have shorter hours. Weather is cool (10-15°C) and rainy. But you'll have the Uffizi almost to yourself.
Savings: 40-60% by switching from peak to shoulder. Another 20-30% from shoulder to low.
Japan (Tokyo, Kyoto, Osaka)
Peak season (late March-April for cherry blossoms, November for autumn colours). Hotels ¥15,000-25,000 per night. Flights from London £600-900. Cherry blossom season is beautiful but packed. Prices are at their highest.
Shoulder season (May-June, September-October). Hotels ¥10,000-15,000 per night. Flights £500-700. Weather is warm in May, hot in June, typhoon risk in September. But prices are lower and crowds are thinner. The Japan Travel Cost Estimator shows a 30-40% difference.
Low season (January-February). Hotels ¥7,000-10,000. Flights £400-600. It's cold (0-10°C). But you'll see snow in the mountains. The Sapporo Snow Festival in February is an exception – prices spike.
Savings: 30-50% from peak to shoulder. Another 20-30% to low.
Thailand (Bangkok, Chiang Mai, Phuket)
Peak season (November-February). Hotels $60-100 per night. Flights from London £500-700. Weather is dry and cool (not cold). It's the best time to visit – and the most expensive.
Shoulder season (March, October). Hotels $40-70. Flights £400-600. March is hot (35°C+). October has rain but usually not all day. Prices are lower.
Low season (May-September). Hotels $20-40. Flights £350-500. Rainy season – but it often rains for an hour in the afternoon, not all day. The beaches can be rough. But you'll save 50-60% compared to peak.
Savings: Peak to low can save you 50-60% on accommodation alone.
Greece (Athens, Santorini, Crete)
Peak season (July-August). Hotels €100-200 on the mainland, €200-400 on the islands. Flights £300-450. Crowded. Hot (35°C). Expensive.
Shoulder season (May-June, September-October). Hotels €50-120 on the mainland, €100-250 on the islands. Flights £150-250. Weather is perfect (22-28°C). The sea is warm in September. This is the sweet spot.
Low season (November-March). Many hotels on islands are closed. Ferries are limited. But Athens is still great. Hotels €30-60. Flights £50-150.
Savings: Shoulder season is 30-50% cheaper than peak, with better weather and fewer crowds.
France (Paris) Peak season (June-August). Hotels €150-300. Flights £150-300. July and August are crowded. August is hot. Parisians leave town.
Shoulder season (April-May, September-October). Hotels €80-150. Flights £100-200. Weather is lovely. Crowds are manageable. This is the best time to visit.
Low season (November-March). Hotels €50-100. Flights £50-150. It's cold and grey. But the Christmas markets are charming.
Savings: Shoulder season saves you 40-60% compared to peak.
The Multi-City Trip Cost Calculator can help you plan a route that avoids peak prices.
A traveller named Rachel used it to plan a 3-week trip to Europe in May. She started in Lisbon (cheap in May), then Madrid (still reasonable), then Barcelona (more expensive), then the French Riviera (peak prices starting). She flipped her itinerary – started in the Riviera, then went to Barcelona, then Madrid, then Lisbon. That saved her €400. The multi-city tool showed her the price differences by week.
Why prices vary so much by season
Supply and demand. In peak season, demand is high. Hotels can fill their rooms at high prices. Airlines can sell seats at high prices. In low season, they discount to fill seats and rooms. A hotel room that costs €50 to operate (cleaning, utilities, staffing) can be sold for €200 in August and €80 in January. The marginal cost is the same. The price is based on what the market will bear.
Exchange rates also play a role. The Currency Budget Converter can help you time your purchase of local currency.
Hidden seasonal costs
Tourist taxes: Some cities increase tourist taxes in peak season. Venice's access fee only applies on certain days – mostly in peak season. Mallorca has a "eco-tax" that's higher in summer.
Flight change fees: If you book a non-refundable flight in peak season and need to change it, the change fee is the same – but the fare difference is larger.
Activity prices: Some tours (like a gondola ride in Venice) cost the same year-round. Others (like a private guide in Rome) charge 20-30% more in peak season.
Minimum night stays: In peak season, hotels often require 3-5 night minimums. In low season, they accept one-night bookings.
How to find the shoulder sweet spot
Not all shoulder season is equal. Early October in Italy is gorgeous. Late October is rainy. Early May is perfect. Late May is crowded. Research your destination's specific shoulder months.
A traveller named Sarah went to Greece in late September. She said "the water was warm, the crowds were gone, the prices were half of July." She used the Trip Cost Estimator to track her daily spending. Her average was €110/day – within her budget.
The one time peak season is worth it
Cherry blossom season in Japan. The northern lights in Iceland in winter. The Venice Carnival. Christmas markets in Germany. These are seasonal events that happen only at certain times. You can't shift them. If you want to see cherry blossoms, you go in April. You pay the peak prices. That's fine. Just know what you're paying for.
A traveller named Mark spent $3,000 on a week in Japan during cherry blossom season. He said "it was worth every penny. I'll never forget it." He had budgeted $2,000. He used his buffer. He was okay with it.
Final advice
Check the Travel Budget Calculator's seasonal toggle. If the difference between peak and shoulder is more than 30%, seriously consider shifting your trip. Use the savings to upgrade your experience – a better hotel, a private tour, a longer trip.
A couple I know, Tim and Laura, shifted their honeymoon from July to September. They saved $2,000. They used the money to add a 3-day safari in Tanzania. They said "September was beautiful. The weather was great. And the safari was unforgettable."
The Multi-City Trip Cost Calculator helped them plan the itinerary – Zanzibar (beach) then Tanzania (safari) then home. They did it in shoulder season for both locations.
Don't assume peak season is the only time to travel. Shoulder season often has better weather (less humid in Asia, less crowded in Europe) and lower prices. Win-win.
The Travel Budget Calculator won't choose your dates for you. But it will show you the cost of your choice. Then you decide.
