But you can go to ANY resort - whatever bus comes first - and switch to a DTD bus from there. Or find a bus that's stopping at Typhoon Lagoon on its way to its resort and switch there.
Thanks for the help. I am thinking that it may be too much trouble to do a park that day then go to Bippity before going to the Grand Floridian for dinner at 1900. If we had a car it would be a different story but I am thinking I may save the money and just spend some extra time in our hotel room doing their hair.
