EMH evenings are on Wednesday nights and the park is open for an additional 3 hours. I've talked to CM's at reservations and they said they have not noticed an increase in ressies for May from last year. I've seen crowd levels being at a 3. A lot of people won't take their kids out of school, spring breaks are over, and the southern state schools aren't even out yet. The summer ressies however are up by 15%! I wouldn't worry too much about it. They would extend hours (like during Easter week) if they noticed larger crowd trends.
