I booked a big bed room in the hotel and he asked me to change rooms. Can I sue him?

It is recommended to negotiate with the hotel.

Whenever the hotel negotiates room change with guests, there will be some problems in the specific operation, which need to be solved by other guests.

If there is no problem with your reservation, the hotel will negotiate with you to change rooms. You have the freedom to change or not, and the hotel has no right to force you.

The hotel or you can propose a suitable compensation plan as long as both parties reach an agreement.

If you don't want to change rooms and the other party forces you to change rooms, you can call the police.
