We really don't partake of the morning hours but the late EMH's are great, cooler, suns down, best time to be in the parks. We always have hopper passes or AP's so we never go to the park during the day that has the extra EMH's, we save that park for the night, enter around 7pm and stay until closing. Definitely better than the morning hours with tons of people trying to cram into the security check. Again as I've always said, Disney will always be there and running around or staying in a park till you drop, can not be alot of fun. Disney is susposed to be relaxing and enjoyment and shared fun, its hot, there are tons of people so go with the flow, take your time to enjoy whats there and leave with the same thoughts as coming, not "I need a vacation from the vacation."
