My kids and I went to Monkey Bizness to get out of the heat and rain yesterday and had a good time. They have "open play" on weekdays. You pay $7.50 and stay as long as you wish to play on the many inflatables. It's a pretty good place to burn off some energy. Remember to bring socks...you have to wear them while you are there (they have some to buy if you forget). My kids loved the giant slide and the obstacle course. They also have regular moon bouces and mini slides and others. My son was disappointed because the rock wall was closed. Apparently they only open it up if they have a ton of kids there. When we went it was pretty quiet - only about 10 other kids or so.
Monkey Bizness specializes in birthdays. They offer many packages which includes play and access to a party room. An example of a package:
The Monkey Around Party: one hour of private platyime and 30 minutes of private party room on Friday after 3 p.m. or anytime on Saturday or Sunday - $195. The party is for up to 25 children and includes invitations, plates, napkins, forks, cups and cake server. (You bring your own cake). For $2.75 a person you can get pizza and soda and they also have decorations and party favors available for a fee.
