Open from 4pm-12midnight for children age 4-12. Cost is $11.50 an hour with a 2 hour minimum, includes dinner. Not bad.
I've seen lots of recent reviews for the one at the Polynesian resort but nothing recent for the Mouseketeer Club at the Grand Floridian. I think our DS5 would have a great time but only if there were lots of other kids there to play with.
Hoping for some recent reviews....
