When I was down that way a couple years ago, I stayed at the Disney World Resort. They have their own campground with shuttles to just about everything or you can drive (if you have a detachable trailer). Either way, it was safe, secure, and convenient. Not the best on price obviously but probably one of the best you will find. We also had dogs with us that played a big role in where we stayed as Disney had a doggy daycare while we went to the parks. Just a thought, but in that area, you might be better off spending a few extra bux to be safer and have access to their transportation.
