3 nights vs 4 nights: which gets you more value from a package deal?

Every time I sit down to book a weekend away from Stansted or Luton, the same question comes up before I've even picked a city: three nights or four? It sounds like a trivial scheduling detail, but it quietly decides whether your trip feels like a proper break or a rushed errand with a suitcase. It also decides whether you're getting good value or just good marketing.

The honest answer is that neither length wins outright. But once you understand how the maths actually works on a flight-plus-stay package, you can stop guessing and start picking the length that suits the city, the season, and your actual budget.

Why the extra night is rarely proportionate

Here's the bit that surprises people. The flight cost in your package is fixed the moment you choose your dates. Whether you stay two nights or five, you've paid the same for those seats. So the only variable actually moving when you add a night is the hotel rate, and hotel rates on a per-night basis tend to fall, not rise, the longer you stay. Many properties price a fourth night cheaper than the first three, especially outside peak weekends.

That means a 4-night package is very often better value per night than a 3-night one, even though the total price is higher. You're not paying more for the privilege of an extra day, you're usually paying less per day for it. The trap is looking only at the headline total and assuming shorter must mean cheaper. It doesn't always.

Our London package checks show this play out across current live packages: a Bergamo (Milan) Lowest packages sits at £86 per adult, Berlin at £99, Porto at £109, Alicante also at £109, and Madrid at £111, all as of 16 August 2026. Spread any of those across a 3-night stay versus a 4-night stay at the same hotel, and the per-night cost of the fourth night is frequently the cheapest of the trip.

When three nights genuinely wins

I'm not going to pretend four nights is always the smarter buy, because it isn't. Three nights make more sense in a few specific situations.

• Short-haul cities you can properly cover in two full days. Alicante, for example, doesn't need four days unless you're combining it with a coastal wander or a day trip. Two full days plus travel days is often enough.
• Peak weekends where hotel rates spike. If a city has an event, a bank holiday, or a festival pushing nightly rates up, the marginal night can suddenly cost more than the average, not less. Check before assuming the discount pattern holds.
• Tight annual leave. If you're doing a Friday-to-Monday from Stansted and using only one day of holiday, three nights is the natural shape and stretching to four means burning an extra day off work you might want to save for later in the year.
• You're testing a city. First visit to Porto or Milan and not sure you'll love it? Three nights de-risks the trip without wasting a full extra day if it turns out not to be your thing.

When four nights earns its keep

Four nights comes into its own in a specific set of circumstances too, and they're worth knowing before you default to the shorter option out of habit.

• Cities with real depth. Rome, Madrid, and Lisbon all reward a fourth day. You stop rushing between the obvious sights and start finding the neighbourhood you'd actually want to live in.
• Shoulder season stays. Outside July and August, hotels in most of our bookable cities have more rooms to fill, so nightly rates soften and that fourth night becomes genuinely cheap rather than just theoretically cheap.
• You want a proper rest, not just a change of scenery. Three nights is arrival, one full day, departure. That's a lot of transit for not much lying-in-the-sun time. Four nights gives you two full unhurried days.
• Flight timing is awkward either way. If your outbound is a 6am Stansted departure and your return is a late-evening Luton landing, you're already losing chunks of two days to travel. A third full day helps that math feel worthwhile.

Working out the real per-night cost

The only way to compare properly is to divide the total package price by the number of nights and look at what you're actually paying per night, not per trip. It sounds obvious, but most people compare the two headline totals side by side and pick whichever number looks smaller, which almost always means picking three nights regardless of whether it's the better deal.

City	Lowest packages (per adult)	As of
Bergamo (Milan)	£86	16 Aug 2026
Berlin	£99	16 Aug 2026
Porto	£109	16 Aug 2026
Alicante	£109	16 Aug 2026
Madrid	£111	16 Aug 2026

Those are current lowest price we saws, not what every hotel in every city charges, but they're a useful anchor. If a 4-night version of a package is only £15 to £20 more than the 3-night version at the same guest score, you're almost certainly better off taking the extra night. If it's £50 or £60 more, the maths tips back the other way and three nights becomes the sharper booking.

Don't let a longer stay drag your hotel quality down

One thing worth watching: when travellers stretch from three nights to four on a fixed budget, they sometimes quietly trade down on hotel quality to keep the total similar. That's a false economy. A guest score of 8.0 and above with at least 50 reviews is the floor worth holding, whichever length you book. A cheaper fourth night at a 6.5-star property isn't a bargain, it's a worse holiday with extra admin.

Check the star rating alongside the guest score too, when it's shown. A 3-star hotel with an 8.4 guest score in a good location will usually beat a 4-star with a 7.9 score and a longer walk to the centre. Don't let the star count alone do the deciding.

A quick city-by-city steer

Since the whole point of a package is flight plus stay together, here's how I'd lean for a first-timer on each of our current bookable cities, based on what typically suits the destination rather than a fixed rule.

• Barcelona: four nights if you can manage it. There's a beach, a hill, two very different old towns, and enough restaurants to need the extra evening.
• Madrid: four nights. It's a walking city with serious depth, and the current Lowest packages of £111 per adult makes the extra night an easy add if the hotel rate cooperates.
• Lisbon: four nights, especially if you fancy a half-day out to Sintra or Cascais, which eats into your city time otherwise.
• Rome: four nights minimum. Three nights in Rome always feels like a highlights reel rather than a holiday.
• Milan (Bergamo): three nights is usually plenty unless you're combining with the Lakes. At a £86 Lowest packages, even a shorter trip feels like strong value.
• Alicante: three nights for a straightforward weekend, four if you're using it as a base for the coast.
• Berlin: four nights. It's a sprawling city and the £99 floor leaves room to add a night without the total getting silly.
• Palma: three or four depending on whether you're beach-focused or exploring the rest of Mallorca; beach-only trips can comfortably do three.
• Porto: four nights if you can, three if you're tight on time. At £109, Porto rewards a slower pace, and a day trip to the Douro Valley genuinely needs the extra night either side.

The booking habit that actually saves money

Rather than deciding in advance "I always do three nights" or "I always do four," check both lengths every time you shortlist a trip. It takes an extra minute and it's the single easiest way to spot when a package deal is genuinely earning its price versus when it's just a longer stay padded onto a fixed flight cost. Prices move fast on Stansted and Luton routes, and the gap between three and four nights can shrink or widen from one week to the next depending on hotel occupancy.

If you're weighing this up for an upcoming trip, have a browse through current weekend and city-break packages from London and compare both lengths side by side on the same hotel where you can. It's the fastest way to see whether the extra night is a genuine saving or just extra spend dressed up as one.

And if you're not booking imminently but want to catch the moment a city drops below its usual range, whichever length you prefer, set up price alerts so you're not the one manually checking every few days. Let the drop come to you, then decide on nights once you can see the real numbers in front of you.

The short version

Four nights usually wins on value per night because the flight cost is already sunk and hotel rates tend to soften the longer you stay. Three nights wins when annual leave is tight, the destination doesn't need four full days, or you've hit a peak weekend where rates spike rather than soften. Either way, don't compare headline totals, compare per-night cost at a guest score of 8.0 or above, and let the actual numbers on the day decide rather than a habit you've never questioned.
