I'm sure a lot of people have different stragedies, including making use of the "Universal Express" Fast-passes. But if you want to go at it the old-fashioned way, what I would suggest is that, upon entering, you make an immediate left into Marvel Super Hero island. Try and control yourself and bypass Hulk. Instead go straight to Spiderman. After Spidey, backtrack to Dr. Doom (space shot) and then Hulk. At that point, if you want to get wet, go to Toon Lagoon and do Popeye and Dudley. Then just continue around the park in a Clockwise manner.
IMO, IOA is an easy park to conquer in an average day as there is more to see than there is to do. But no matter what, make sure that you ride the Blue Dragon in the front seat!
Have an ICE ride!
