Take the credit card of China Merchants Bank as an example. The normal operation of staying in a hotel is to swipe the credit card for deposit first, and then deduct it directly from the deposit when you actually check out, so as to release the remaining credit limit. However, at present, some hotels will swipe their cards twice, first by swiping the deposit, and then by swiping the bill. The deposit will be cancelled later, and you don't have to pay the deposit (the deposit will not be displayed on the bill for repayment). The cancellation time of the deposit is longer or shorter. If you think that occupying your credit limit may bring you inconvenience in using the credit card limit, you can promptly notify and remind the hotel to cancel it for you.
