If you go to Universal Islands of Adventure, the dueling dragons are alot faster to get on then the Hulk, especially towards the end of the day. The last 4 times I've gone, we were able to get on it with no longer then a half hour wait. When the hubby and I went by ourselves, we managed to ride 6 times in 2 hours... I was dizzy for an hour after
Haven't been to Disney yet (we get a different annual pass every year) but my sis said Animal Kingdom is great.
