We were there last year for July 4th. Yes, it's busy--yes, it's hot- BUT--we loved it so much we're doing it again this year!! Just made our ressies last week. The fireworks were just on the 4th and they were fantastic. Hope they're as good this year! Staying on site with the express access was so wonderful. It didn't matter how big the crowds were. We went in the AM--then came back to relax at the pool--then went back for dinner and more rides in the evening. The parks at night are great.
