I nkow you've had a million replieds already, but I live here in Orlando (like some of thos that replied). I have been there many, many, many times and I personally found this to be the plan of attack:
First, go straight to The Hulk (as others have said). If you hurry, you should be able to ride it at least 2x before the line is long. Also, I highly, highly recommend riding front row the first time you ride it. Then back row.
Additonally, Spider-Man is not a coaster, but one the best rides I have ever been on. It is unexplainable.
If you really want to go straight to Dueling Dragons, keep in mind - it is on the opposite side of the park. The queue line for it is one of the coolest I have ever seen. I recommend riding both fire and ice. They are entirely different rides. Front row makes a huge difference on these, mostly because of the "appraoch scenes" to the other coaster (and the walls).
I also recommend checking out:
-Jurrasic Park Rive Ride
-Dr. Doom's FearFall (upward launch "drop tower")
...and if you have time, check out the show over at The Lost Continent (used to be called Posieden's Fury or something like that). Also, the water rides on toon Lagoon are fun......and I know you said you don;t have any interest in Cat in The Hat - but if you have time, it's worth 1 ride just for the theming. As with nay park, don't go to lunch at "lunch time", that's when all the lines are potentially shorter.
-Hope I didn't repeat too much of what you already read. Have fun!
