God, no. Get on a plane!
What do you enjoy? Rides, shows, animals, movies, water parks, etc.?
If I were going down in August by myself, I'd do the water parks (didn't do that this year, not warm enough) and Epcot, and if I hadn't already seen them, Animal Kingdom and Magic Kingdom in that order of preference. I'm not real interested in movies. Also I highly suggest getting the dining plan. It's no fun to worry about how much things cost; on vacation I just like to pig out!
Or maybe, if it were me, I'd just say to hell with it and go to the beach.
