You can walk right on in, but as multiple others here have stated, it's strongly recommended that you reserve in advance.
You can walk in, but it's easier when you reserve the spot, so you know for sure you are going to get into the room.
If you're going with a group of people I would definitely suggest reserving a time because depending on the room that you are going into some rooms have a limit of 10 people and some have a limit of 12.
Reservations are highly recommend. Especially if you have a larger group. You can walk in, but reservations are given priority and walk-ins will be added to other groups.
There is a limit on the number of people in a room and each room is on a schedule. It's definitely best to book in advance to ensure you have a place in the room.
I s suggest you make reservations to ensure your spot.
