I live in Frisco. I am not sure if this what your looking for but every Wednesday Kurt Thomas gym has an open gym for preschoolers from 10:00am to 11:15am. My son loves it because he can do what ever he wants. It is a full gym. It cost seven dollars. It is on Frisco street behind the Power house. Their number is ###-###-####. There is not commitment you just pay seven dollars if you go. Also right by there is a Pump It Up and it has an open preschool thing on Mondays at 10:00am to 11:30am. It cost about the same. Their number is ###-###-####. I hope that helps.
