The playground is large and my kids had a blast (They are 6 and 4). All the kids that were in there started playing tag and my kids were sweaty and happy and laughing the entire time. They slept really well that night too!
This playground is also completely FREE. You just walk in and stay as long as you like. Of course if your kids are like mine they will prob not stop pestering you for money to play video games and buy snacks....but it's still technically free lol.
