Personally, I enjoy the walk, if it's not 100 degrees with 100% humidity!!!!
I enjoy walking on Disney's Boardwalk. Although it is a rather long walk I have always noticed that the boat takes FOREVER!!!!!!!!!!!!!!!! The only reason I would take the boat is if the heat is unbearable!!!!!! But usually once I'm down there for about 3 days of so I get used to the heat. Trust me, going from Cleveland weather to Orlando weather is aweful!!!!!!! That first day is a killer!!!!
Just to illustrate how slow the boat moves, Indy 95 and I, beat the boat in a race from MGM to the Boardwalk!!!!! He got quite an ovation from the people on board the boat. They LOVED IT!!!! Trust me, Indy 95 (my cousin) has CM written all over him.
