Will there be a blacklist for hotels in Germany?

No blacklist.

Hotels are in the service industry and generally will not blacklist guests easily. The hotel may blacklist a guest if the guest's behavior poses a risk or threatens the safety of the hotel and hotel employees. Generally, before a blacklist is made, criticism from the hotel general manager or even the group headquarters is required before it can be implemented. Generally, people who are blacklisted by hotels have the following three situations:

1. Damage to the hotel economy.

2. Damage the safety or reputation of the hotel.

3. Threaten the safety of hotel employees.
