How to open the door when one is out of the hotel and the other is asleep in the room?

You can try the following methods for this behavior:

1. Contact the front desk: You can contact the front desk staff of the hotel to inform the situation and request help. The front desk staff will usually try to help you solve your problem.

2. Use a spare key: If you have a spare key, you can use the spare key to enter the room. Using a spare key can cause unnecessary trouble for the hotel, so be sure to use it in an emergency.

3. Contact hotel security: If you cannot contact the front desk or the spare key is not available, you can seek help from the hotel's security staff.
