What is the retail price and the front desk payment price of the hotel?

The retail price is the listed price of the hotel (for example, the price when you go to buy clothes), and the front desk payment price is the price you actually consume (for example, the transaction price after bargaining with the merchant at last when you buy clothes). The reservation price is definitely cheaper than the front desk, and there will be no room at the hotel. If you don't understand anything, you can reply to me.
