SkyZone has its party process dialed in.
Other than the waivers taking forever to fill out (highly recommend getting your guests to do it ahead of time), everything is super easy because they handle everything - from the carts with the birthday child's name on it, to the clean and pre-arranged assigned room, to the party host or hostess who is trained well on how to handle kids, parents, the cleanup process, and everything in between.
Every staff person I've met has been very nice and efficient at their job.
The reason I give it 4 stars is that despite there being an express, "members" check-in line, it can still take up to 10-15 minutes because there are only 3 computers to scan people in and during busy times of day, it can get really backed up. Also, the female bathroom never seems clean enough.
