Call the park and see what they can do to accommodate your request.
Like Cecilia stated above, yes the restaurants do help you celebrate but you have to bring your own paper hats, small decorations, etc. They'll give you a sticker the child can wear and staff throughout the park always go out of their way to wish the child a happy birthday!
At the restaurants they do...and I think they give u a birthday pin as well...like in Disney
I can't really help you with that question because I don't know myself.but it will be worth going either way.
