The Play N' Learn Free Play Days offer parents and kids a way to get out of the weather while playing on playground equipment in the showroom from 10- 1 on Monday and Thursdays. They also have netted trampolines and basketball hoops for the kids to test out. The showroom flooring is just carpet over concrete so just be aware if the kids fall they might hurt themselves. There are super clean restrooms and water fountains. It was very popular when we went and from what I understand they don't put a cap on attendance and the play time is for the 6 and under crowd.
I talked with one of the sales reps and she told me that if you are a customer of Play N' Learn you can come and play any day as a bonus for buying their product. If you live in the area you should go check out the Free Play Days at Play N' Learn Playground Superstore!
