The Hotel Order Tax: Same 3 Spain Hotels, $1,654 Apart Just by City Order

• Same hotels, same 12 nights, same dates: the city order alone moved the total by $1,653.66.
• Allowing departure to shift by up to two days widened the spread to $2,528.76 across 30 combinations.
• The cheapest order (Madrid → Seville → Barcelona) includes a 5+ hour Seville–Barcelona train. Putting Madrid in the middle costs $469.85 more but splits the trip into two ~2½-hour trains.
• There is no universal "cheapest day to leave": each city order had its own best departure date.

The trip we tested

The hotels were fixed in advance. The only questions were: which city first, and which day to leave?

Does city order affect hotel prices? Yes: here are all 6 orders

All six orders below use the same three hotels, four nights each, starting February 1. Each total is the cheapest available offer for those exact dates.

Spread: $9,283.42 − $7,629.76 = $1,653.66.

The two Barcelona-first orders are the outliers, both above $9,200. Part of that comes from what Barcelona had available on February 1–5: the cheapest bookable room that week was a larger Deluxe Santa Caterina King with breakfast, rather than the standard room available later in the trip. That is typical of how the order tax works. The hotel does not change, but the room types and rates available on your specific nights do.

Where the money goes in the cheapest order

Madrid is more than half the bill. When one hotel dominates the total, its date sensitivity usually decides which order wins.

What happens when you also move the departure date?

Next we let the departure date move up to two days in either direction, from January 30 to February 3. That gives 6 orders × 5 dates = 30 combinations.

Bold marks each order's cheapest departure. All totals are USD for 12 nights.

• Cheapest of all 30: leave January 30, order A, $7,335.55. That is $294.21 less than the best February 1 option.
• Most expensive of all 30: leave February 2, order F, $9,864.31.
• Full spread: $9,864.31 − $7,335.55 = $2,528.76.

Two patterns stand out:

1. The best date depends on the order. Orders A, C and F were cheapest leaving January 30. Orders D and E were cheapest leaving February 3. Order B was cheapest on the original February 1. A rule like "always leave midweek" would have missed half of these.
2. One day can swing an order by hundreds. Order A jumps from $7,629.76 on February 1 to $8,292.44 on February 2, a $662.68 difference for leaving one day later.

The cheapest itinerary, night by night

Is the cheapest hotel order also the best route? Not always

Cheapest is not automatically best. Order A sends you Madrid → Seville → Barcelona, and the Seville–Barcelona leg is long: the fastest advertised rail journey starts at around 5 hours 18 minutes. Putting Madrid in the middle (Seville → Madrid → Barcelona) turns the trip into two high-speed legs of roughly 2½ hours each.

So the real decision is money versus time: about $470 to save roughly three hours on trains and avoid backtracking through the Madrid corridor. Neither answer is wrong, but you should make the choice knowingly instead of by accident. Train times above are general journey times, not verified February departures; check current Renfe or Iryo schedules before booking. Flights from London and train fares were not included in this comparison.

Why nobody catches the hotel order tax

Finding the $2,529 gap took 30 combinations, which means 90 separate hotel price checks (three hotels per combination), all on live rates that can change between searches. Very few travelers do that by hand. General AI chatbots can suggest a sensible route, but without live inventory they estimate prices instead of quoting them.

For this test we used the Fortrip plugin inside ChatGPT, which pulls live hotel rates for every combination and can set up the hotel orders once you pick one. You can also run the same comparison directly in the Fortrip trip planner.

How to check the order tax on your own multi-city trip

1. Lock the hotels and nights first. Keep the comparison fair: same properties, same number of nights per city.
2. List only the orders that make sense geographically. Drop routes that force long backtracks unless you are happy with the extra travel.
3. Add a ±2-day departure window if your dates have any flexibility. In this test, that added another $875 on top of the order effect.
4. Find the hotel that dominates the bill. Here, Madrid was over half the total, so its nightly rates drove the result.
5. Check room types and fees. The cheapest offer can change room category, breakfast or cancellation terms between dates. In this case all three winning offers were room-only and non-refundable, and Barcelona quoted a separate local property tax of about $59.
6. Weigh the transport trade-off before booking the cheapest order.
7. Book soon after you compare. Live rates are not held; the numbers above were valid on November 8, 2026.

FAQ

What is the best order to visit Madrid, Seville and Barcelona?

For hotel cost alone, Madrid → Seville → Barcelona was cheapest in our test, at $7,629.76 for 12 nights on February 1, 2027 departure dates and $7,335.55 leaving January 30. For the easiest train travel, Seville → Madrid → Barcelona avoids the 5+ hour Seville–Barcelona leg and cost $469.85 more on the same January 30 dates.

Does the order of cities really change hotel prices?

Yes. Hotel rates are set per night, so visiting a city earlier or later in your trip changes which nights you pay for. With identical hotels and nights, the six orders in this test ranged from $7,629.76 to $9,283.42.

What is the hotel order tax?

It is the extra amount you pay purely because of the sequence and dates of your hotel stays, not because of a better room or more nights. In this Spain trip it was $1,653.66 from order alone and $2,528.76 once departure dates could shift by two days.

Is it cheaper to leave a day or two earlier?

Sometimes, but not consistently. Three of the six orders were cheapest leaving two days earlier, two were cheapest leaving two days later, and one was cheapest on the original date. The only way to know is to price each order on each date.

How long is the train from Seville to Barcelona?

The fastest advertised rail journeys start at around 5 hours 18 minutes. Seville–Madrid and Madrid–Barcelona each take roughly 2½ hours on the fastest trains. Check current schedules for your dates.

Do these prices include flights and taxes?

No. All totals are hotel-only, in USD, for 1 adult and 1 room. Flights and trains are excluded. Barcelona also quoted a separate mandatory local property tax of about $58.70–$58.87 for some orders, payable at the hotel.

Can I run this comparison for my own trip?

Yes. Paste your hotels, cities and dates into Fortrip, or add the Fortrip plugin to ChatGPT, and ask it to compare every sensible order and nearby departure date with live prices.
