Girlfriend 18 birthday is coming. How should I decorate the atmosphere of my hotel room?

First, you need to book a room in the hotel. You'd better pay a deposit to book a room you like, and try to choose a bigger one with a big bed.

Since it's your girlfriend's birthday, I don't know whether you choose a romantic one for two or a lively one for friends and family. The former is usually at night, and the necessary things are cakes, red wine, candles, soft pure music, and then knocked down. . . . . .

The latter is to invite friends and relatives to join in the fun and dance together.

The layout of the room is to hang some colorful balloons, some flowers and so on.
