I think that is ideal, you get to do all you want but still have the potential to come home rested! Awesome. I don't think I could stay that long in a value though, though they are great...I agree w/the pps who want laundry and a home cooked meal. A villa would be ideal, or a FW cabin(if only they had a w/d,lol) but a real fridge to be able to use up leftovers or get some lunch fixings, that kind of thing would really be good. Don't get me wrong, I am NOT into cooking on vacation, but 10d of eating every meal on property could get mighty expensive, boring and calorie dense, lol. But if you are doing those other things, you'll have a car?? So a grocery run would be easy. Plus, we found some nice off-site dining last time and can't wait to go back to one place in particular--Mimi's Cafe, up by Millenia Mall area.
Lucky you!!!!
PS--haven't done Seaworld but love KSC. There are so many things I would try if time permitted--Gatorland is on my list too.
