Yes, their individuals and other groups in there at the same time.
You can go in with your own group or alone. It is more fun to bring friends. You can also go thru as many times as you like challenging each other to make it faster. You get very twisted around with 2 different entrance/exits. I am speaking from experience. We had a blast!!!!
There is only one maze, so, yes, your group can go in together, and there will be other groups too.
Yes they'll let you go in with other people... even when you go in at intervals you'll most probably bump into someone (if not your self in the mirroe) at some point. Always have your hands in front of you!
Most likely no Its very narrow and other people are in there with u Theyll probably tell u to leave it in the lobby
