You have probably heard this over and over, but don't miss Spiderman. It is awesome. If you like thrill rides, do Hulk and Dueling Dragons. They are great coasters. I don't know how busy it is going to be at this time of year, but at IoA head to Spiderman first thing then do the coasters. At USF, I would start with MIB and BTTF and move on from there. There is a fast pass type system on two rides at USF (not sure which two) and on JPRA and Posidens Fury at IoA. I didn't use it when I was there so I am not sure how it works. There is something called Universal Express that was in effect when i was there, but I heard they are going to change it so I don't know if it is the same as when we visited. Hopefully someone who has been recently can let you know if that is still available. Hope I shed some light on things for you. Have a great trip
Been there, done that, going back!!!
