I attended a 2nd birthday party for yelper-in-training, Eliana L, at Scottsdale Gymnastics today. There were a ton of kids and parents there, and everyone seemed to be having a great time.
The staff interacted well with the kids and got them to play games, take pictures, and even use hand sanitizer prior to heading into the main room for lunch.
The facility is larger than you can imagine, clean enough, and appears to be a great place for a kids' birthday party... with Baby M arriving any day now, I am trying to find places that may be appealing for playdates, classes, etc... down the road, and I will definitely keep this place in mind.
