Do I need a check-out card to leave Sheraton Zhengzhou Hotel?

Of course, you need a check-out card to stay in the hotel. The room card is your most important housing certificate. Only when you have a room card can you open the room door to ensure basic safety.

Therefore, when you check in, you should take good care of your room card to prevent others from finding it or losing it. Finally, when you check out, you should return the room card to the front desk, so that you can formally go through the formalities and refund the housing deposit.
