What do you mean by hotel upgrade?

1. interior decoration: after the hotel has been opened for a certain number of years, the room facilities will be damaged and aged with consumption. In order to meet the needs of the market and guests, the room will be renovated and the hotel hardware facilities will be updated. Also called room upgrade.

2. solving complaints: this is more complicated. Simply put, you booked a hotel room, but for various reasons, the hotel didn't arrange it for you. When you arrived at the hotel, the room you reserved was gone. At this time, in order to solve your problem, the hotel upgraded your room, that is, for example, you booked a standard room and upgraded to a deluxe standard room or a better room, but the standard room still needs to be charged. That's it.
