I went from the 23rd to the 30th last year. It was more crowded than I expected, so this year we are HOPING to be able to go the the first or second week of May. THe weather was HOT and gorgeous. I really liked May. THe only other time I have gone was in June which of course was also hot, but I must say I would not be interested in going in the cooler months. I like the hot weather.
