Pre-authorization means that the hotel will freeze 1000 yuan in your card. Generally, you don't need to open a credit card, but you bring it with you.

In other words, the hotel will freeze the 1000 yuan in your card when you check in, and then swipe your card when you leave, only deducting 800 yuan. There is no question of 200 left. After deducting 800, the remaining money is still in your card. You got it?
