My friend lives in a hotel. Can I go up for a while?

If you are a friend staying in a hotel, you can visit, but you need to abide by the rules and etiquette of the hotel.

First of all, you need to contact your friends in advance and get their consent. If a friend agrees to let you visit, you need to abide by the rules and etiquette of the hotel, such as dressing appropriately, not smoking in the room, avoiding affecting the rest of other guests and so on.

In addition, if you want to enter a friend's room, you need to make sure that you have checked in or are a hotel guest. If you don't check in or are not a hotel guest, the hotel may prohibit you from entering the room.

In short, if you want to visit friends, you need to abide by the rules and etiquette of the hotel and respect the rights and interests of other guests.
