Spider-man is an amazing ride where you sit in 6-axis motion simulators (cars that turn and move in 3D) which move along a track through the ride, and 3D images are projected around you (you wear 3D polarized goggles). My favourite ride in IOA, slightly ahead of the newer HPFJ. Actually, Spider-man is my favourite ride anywhere. Also a big fan of Popeye and Bluto's Bilge Rat Barges - but you know, you will get wet.
I also have a soft spot for taking an afternoon break at the Watering Hole, a take-out in Jurassic Park near WWoHP. Just something about the atmosphere, or ambiance, or some other intangibles.
I'd consider lunch at Mythos, too. Not typical theme park food.
