Hi!
We had our daughter's party at Gymboree and all the kids had a blast! They do parties for kids up to 5 years old and they're really good at parties for multiple age groups (if you have siblings or cousins or something like that coming). They do absolutely everything so no work for you!! They also can do themes so you could still do a pirate party and they make up activities for the kids to do on their equipment like walking the plank or whatever. Have fun!!
