When to book a hotel: the answer isn't "as early as possible"

People ask me all the time how far ahead they should book, and for years I gave a vague answer like "it depends." Then I actually started looking at the data, and it turns out it really does depend, but on one specific thing: how tight the room supply is in that destination, for those dates.

A forty room hotel in a mountain village during the August bank holiday can't conjure up extra rooms. Once it's full, it's full, and whoever books late pays for everyone else's procrastination. That's as true for the Dolomites in mid August as it is for a three star place on the coast during peak beach season. If the property is small and the date is popular, booking a few months out isn't anxious behavior. It's just doing the math.

The last minute myth

Last minute deals work brilliantly where supply is abundant. A city with four hundred hotels will dump unsold rooms in the final days, and a decent hotel can cost thirty percent less on a Tuesday for a Thursday stay. Bologna outside of trade fair season, Vienna in November, a quiet weekend in Turin with nothing on: that's where waiting pays off. But try finding a last minute deal on a Tuscan farmhouse in June. It doesn't exist, and anyone promising you one is selling scraps.

There's also a window almost nobody uses, somewhere between sixty and ninety days before departure. Hotels watch how their bookings are filling up and quietly adjust prices, no announced sale, nothing flagged anywhere. Anyone who checks rates in exactly that window often finds the lowest point on the whole curve, even for hotels that aren't especially fancy.

What to actually do

Book early what's scarce (few rooms, a local event, a strong high season) and wait on what's abundant. And if you do book far ahead, almost always pick a cancellable rate: lock in today's price, keep the freedom to rebook if you find something cheaper in two months. That's not a clever trick. It's just reading the terms the hotel already offers you.

One last note on the day of the week you book. Some people swear Sundays are cheaper. In the numbers I look at, the difference is real but small, a couple of percentage points at most. What matters far more is when you sleep, not when you click. Shifting your stay by a week is often worth ten times more than waiting for the perfect moment to hit send.
