We came with a group for the Zombie Apocalypse experience. The wait time outside was about 30 minutes, which wasn't horrible. We were given guns (mine luckily functioned! use the short-stock option) and then we were released into the maze. We came with a group of 6 people, but we took the recommendation to split up into two teams of 3 people each. Definitely split your group if you can - otherwise you won't see as many zombies. At the door, we were told to sign a waiver since the zombies can touch you; not sure how I feel about that. Luckily none of the zombies got a chance - my team of 3 had an ex-military guy covering our 6 while my husband took point, and I took the precaution of shooting each downed zombie in the head three times as I passed them. I might have yelled "stay down!" a lot while doing it.
If you come in prepared with an athletic team, ready to run, you'll be through in 10 minutes. That's my main issue - $30 is $20 too much for this experience. $10/person is much more reasonable for the amount of time you spend in the maze.
