I'm hoping it is not crowded in May, our trip is planned for May 12-19. I think that towards the end of the summer (late june and on) that the crowd tends to pick up. At least you can take advantage of the EMH's if you are staying at a resort. Our problem is is that there arent a lot of EMH's the week we are going (there are usually 2 a day in the summer) so I'm hoping that means that it wont be too busy and we will get everything done and heaven forbid be bored during the day/nite. My advice is plan ahead, see where you want to eat and correspond with the schedule of the days you are going and what parks have EMHs if you are going to do those, hope this helps!!
