We were just in Orlando and stayed down the street from HIFS at the Sheraton Vistana Villages for a 10 day stay.
There is plenty to do on Int'l Drive...great restaurants, shopping, Ripleys Believe It or Not, some NASCAR themed place (sorry, going by a visual in my head), FAO Schwartz, tons to see and do if you drive over there. Inquire at the hotels' front desk, there's tons of brochures and papers to browse thru too.
We were so tired at the end of the day, that by 7:00 PM we were in our vehicle headed back to the resort and either ate there or went out to eat, then relaxed with the kids by the pool for the rest of the evening.
We managed to go to Daytona Beach 2x, we visited the race track for pictures as well.
We also went to Downtown Disney one night and walked around, it was a beautiful night, lots to do here too.
We checked out the Yacht & Beach Club (Wow!) Stormalong bay and took pic's from the ferry boat, etc. We ate at Beaches & Cream (excellent burgers & chix sands, $$ but worth every bite!) My kids were too tired afterward to walk the boardwalk, though it looked like alot of fun.
We did not resort hop to any others- we just didn't find the time, although I really would have liked to.
I'm sure someone will be along shortly to give you more/better information...have a great vacation.
