Believe me, I have stayed in many hotels on business, and sometimes hotel rooms are very tight during holidays and tourist peaks. If you don't make a reservation at night, they will risk losing a room, so you have to pay a deposit to reduce their risk. It's actually quite simple. If you call the front desk of the other hotel and the other party asks you to pay, you can pay. How can you say that you won't be greedy for your money if you invest hundreds of millions in the country for seven days? In the off-season, my buddy upstairs said the same thing.
