Quick advice...
In mid-September it is certainly possible to do most of the attractions in both parks in one day. I suggest Monday or Tuesday - they are the least crowded days of the week at Uni. Get there at park opening. As soon as you arrive, pick up a park map to help you navigate.
In USF, don't miss T2:3D, Men In Black, Jaws, Mummy's Revenge, Twister, Shrek, the ET Adventure, and Back to the Future.
In IOA, don't miss Spider-Man (thrill), Hulk (coaster), Jurassic Park River Adventure (non-thrill, a little wet), Posiedon's Fury (stand-up show, amazing effects!), Eight Voyage of Sinbad (sit-down stunt show with comedy, very funny) and Dueling Dragons (steel racing coaster- I prefer Ice). If you are a thrill-seeker, you can also try Dr. Doom's Fear Fall. If you want water, try Ripsaw Falls and Bilge-Rat Barges (SUPER wet!)
For lunch, try Mythos in IOA - fantastic food, sit-down restaurant.
For dinner, try one of the restaurants in teh resorts or in CityWalk.
TicketMania delivers to all hotels in the Universal/I-drive area. Order soon! They will need to contact you to confirm your resort location and check-in date for delivery. But if you have a car, you can also pick up from their office, which is not far from Uni. Check their web site for directions.
Have fun.
