Every day through 8/26, The Disney Store is offering fun play days for kids ages 3+. The activities vary from crafts, art activities, singing, dance, movement etc. Each store has it's own schedule that changes every week, so you need to call your local store to find out the times. More information is available on the Facebook Event page.
If you attend 4 times, your child gets a prize, so make sure you get a stamp card when you attend.
I took my kids this week. They got paper Mickey ears and learned the Hot Dog dance, and had a lot of fun. My son is not 3 yet, but they didn't ask or care.
