Innoventions West hallway right behind Club Cool. The A/C and strange persistent smell are just bonuses. There's also lots of cool spots around World Showcase that have benches and are shaded. At the other 3 parks, we are usually more on the go from place to place. Epcot is my "take it all in" park. On our last trip, since it would be the last time I would see ROE, my daughter and I parked it at a picnic table right up next to the lagoon railing near Germany a good 2 hours before the show started. Got to spend time with her while taking in all the preshow loop. My wife had gone back to the room to crash, so the two of us watched the show then walked out singing "Promise" at a pretty good volume like two lunatics. Good times.
