Between the two, which would you rather have a 2 year old's birthday party at? Or, which would you rather attend? What are some pros/cons for each?
What I do know is that a party at My Gym is only 1.5 hrs, and all you have to bring is food/drinks and cake. They handle the rest.
At Marbles, you get an hour in a party room, then guests are allowed to play in the common areas of the museum as long as they'd like. They also have a package that even includes a cake, ice cream, and drinks. Both supply plates/cups/etc..
I've never been to either (well, my wedding reception was at Marbles when it was Exploris, but not since the change. hehe). Are the exhibits at Marbles super spread out? It would be hard to keep a group together there, I'd think (not that they'd necessarily have to stay together)...
I've got some time, but I hear Marbles at least books pretty quickly, so I want to make a decision!
