Stay at home for four days Please tell me how to calculate the deposit. ...

Room rate per night 170, 680 for four days. The deposit depends on how much the hotel charges, usually 50 to 100, which has nothing to do with the room rate! If the deposit is 100, you have to pay 780 for the first time, and he will refund the deposit of 100 to you when you check out. It means that you only spent the room rate, and the deposit is only a temporary mortgage.
