It's good to call and set up an appointment. Great place helps you think out of the box
Generally, there are different capacities depending on which room you choose. I'd always recommend booking in advance, especially if you have a large group. I'd call Trapped! if you are organizing something for a larger group that may need multiple rooms or times.
A reservation is highly recommended. I think they might let you pretty the door, but a reservation will ensure a room is available. As for people, they currently have two rooms: one for 8 people and the other for 7.
