If there's one thing that I love getting to experience more than any of the actual attractions, it's the ambiance right outside the entrance to Islands of Adventure. That early morning sunshine, Hulk roaring around the track as, with the park entrance music playing as you anxiously cross the bridge towards the front gates is just *chefs kiss* perfection.
To me, it's is as good as the Main Street reveal at Magic Kingdom.Both just never get old. I'll take both of those moments over any of the attractions in either park.
