Well, I've heard that, but I can't speak from personal experience so I didn't bring it up. But when it comes to hauling around toddlers and getting old, there I know whereof I speak!
The idea that walking to the parks from the average Disney parking lot is not a hardship for some, or that the lack of trams is not a big deal, just boggles my mind. As you point out, normally Disney makes hard to make everyone feel welcome (hubby avoids dairy and Disney's better about that than most) -- and making people walk that far across blacktop in the Florida heat is not very welcoming.
