No, sorry, I don't. However, I don't really think you need one. There's a map right as you enter the park, and once you get your bearings, you really should have no idea finding rides or getting from place to place. It's not big at all.
Of course, you might be looking for one for a website you're making or something, thus rendering all the information I just typed completely useless... ;)
