two hours should be plenty of time if you've already done the check-in.
As another poster said, Orlando airport is quite nice. There's even a
disney store there....and i think a universal one as well (or a warner brothers one)..
just in case you didn't buy enough stuffed animals while visiting the parks...
i see you're staying at Old Key West....you're going to love it there...
it really feels like going home...
if you rent a car, when you drive though the security gate, the guard waves and says "welcome home" every time you drive through....call me corny, but i just love that...
and the people working in the little souvenir shop in the main building are as nice as can be....as are CMs who check you in....
and the room.....we stayed in a 2 bedroom villa when we were there...wow....absolutely HUGE.....
the only drawback is the pool...not very nice...but i hear they're building a new one, but i don't know when it will be done....
