What is the hotel retail price and average price on Ctrip? Is the price shown on Ctrip. com the money I paid when I stayed in the hotel?

The retail price is the price you pay to the hotel directly. The average price is the average price in a few days. Not necessarily the most expensive on the first day. It depends on the price the hotel gives Ctrip.

for example, if you book for 3 days and the prices are 1, 15 and 2 respectively, then the average price is 15. The price may be different every day. You have to watch it day by day.

whether booking in Ctrip or hotel, you booked for 3 days, so even if the hotel later increases the price of the third day, you still pay the original booking price without increasing it. But if you make a reservation for two days, and say on the third day that I want to stay one more night, the hotel will tell you that it has gone up on the third day, so you have to increase the money.
