The girl goes to the hotel

The answer to this question depends on your relationship and your travel plans.

If you are an ordinary friend and plan to travel, it is usually enough to book a room. For example, if you plan to travel somewhere together, sharing a room can save money and make it easier for you to travel together.

If you have a closer relationship, such as a love relationship, then you may choose to book two rooms, which will give you more private space or enjoy the trip more privately.

Generally speaking, booking a room or two rooms depends mainly on your own needs and comfort. In the case of uncertainty, you can communicate with the other party before booking to clarify the expectations and needs of the other party.
