I used Gymboree for my first born's 1st birthday. My husband was a little hesitant to use them due to the cost ($180). But, in the end i think he was glad we chose them! First, it is an all around safe play place for all young children. Secondly, you do not have to worry about setting up, entertaining, or safety. As soon as you arrive for your scheduled party they begin to set up the present and cake/cupcake eating area. As soon as all of your guests arrive, they begin with fun activities, singing, and free playtime. Once things wind down (you have a set 2 hour time slot) they thank everybody for coming, etc...so, that keeps you from worrying on how to end the party. I believe that it was worth the money for a large guest list (there were 15-20 babies w/ parents at ours)and the relief of any cleanup, entertainment, or safety issues. A bonus is that you can bring your own cake and whatever type of decorations as you want for no extra fee!!!
