How can the hotel protect its rights without hot water?

1. First, complain to the hotel front desk or management, and ask to solve this problem as soon as possible. You can explain the room number and the specific situation that there is no hot water, as well as the measures you want the waiter to take, such as changing rooms or providing other solutions.

2. Finally, if the hotel can't solve the problem, it can consider complaining to the local consumer protection agency or relevant regulatory authorities.
