D.G.
I am having my son'e 4th bday party at Berks Gymnastics (they have 2 sites... you can check them out on the internet). A party for 12 kids is $125. That includes 45 minutes of organized activities in the room and then 45 minutes in a side room where you can bring your own food. I'm having the party at 1:15 to avoid having to do anything other than cake and juice boxes. I've ordered water bottles as favors and I am going to do a pinata with candy (they will use their personalized water bottles to hold the candy from the pinata). With invites (I ordered post cards from zazzle.com) I should be able to do the party for under $200.
