Birthday parties?!
Answers: What are some good birthday party places to go to in Orlando for an 11 yr old
I don't live in Orlando, but I do have a few suggestions.
11 year olds are usually energetic, so an active party would be best. Maybe take them to a local pool/rent out a pool, but to make it really fun, try a wave pool. Or take them to an amusement park, and have loads of fun going on rides and eating foods like pizza.
Or for 11 year olds who aren't too energetic, try mini golf, ending it with sitting down with pizza and soda. Or then go to go-karting. Or a dinner out at a buffet or live grill is really fun. It's usually fun to see a skilled man or women flipping knives around and making yummy food.
Other ideas: Roller disco? Bowling? Renting out a movie theater and going in your PJ's?
