We are staying at the fort and doing USO and IoA on our next trip. I cant imagine anyreal drawbacks except for transportation from the fort to Universal's area...we prefer not to drive when at Disney...but obviously that wont be an option, no biggie!!! I like that universal has the 2park/7days option for such a low price...that way if we dont wanna spend a whole day there, I wont feel like Im wasting money by leaving early to hang out at the fort. In fact, I only expect to spend about 4 days at the parks and the rest just fishing, relaxing with some beers, looping in my cart, and napping in a hammock at the beach!!!
