Hotel pricing isn't set once and left alone. Revenue management systems reprice rooms multiple times a day, reacting to how many rooms are still open, how similar properties nearby are pricing, and how close the date is getting. Most of that repricing is small and boring — a dollar up, a dollar down. The interesting movement clusters in the final ten days before check-in.
That's the window where a hotel has the clearest picture of how a date is actually going to perform. Thirty days out, a property is still guessing based on historical patterns. Ten days out, it can see its real occupancy for that night and compare it to where it expected to be. If bookings are behind pace, prices come down to fill the gap. If a date has sold out faster than expected, prices climb because the remaining inventory is genuinely scarce.
This cuts both ways, which is exactly why blanket advice like "always book early" or "always wait" doesn't hold up. A popular city-center hotel during a conference week will almost always get more expensive as the date approaches, because demand is real and rooms are limited. A leisure hotel with a slow midweek date is far more likely to drop, because the property would rather fill the room at a discount than have it sit empty.
The practical takeaway isn't to guess which category your hotel falls into — it's to keep watching. A rate that looked locked-in a month out can move meaningfully in either direction as check-in approaches, and the only way to catch a drop is to actually be checking during that window, not just once when you booked.
