We are all under 18, but we have ID cards. Can we have a single room or a double room?

Basically, most hotels are calculated by room, so it is no problem for two people to open a room. But the problem is that you are minors.

But when I 16, I stayed in a hotel alone. Basically, people won't say anything unless you go to a formal place to hang stars.

But out of respect for each other, save more money and open two rooms. Now the room is less than 100, which is not expensive.
