We could have, but opted not to, use the Evening EMH at MK. We were there Presidents week, and the park was already open until midnight, then the EMH had it open until 3AM. We left at 11:30PM, and the park was really empty already, I couldn't imagine the place at 3AM. It is one of those hit or miss things, if you get there and the park is filled, it probably will remain filled, if it is empty it is only going to empty out.

My recomendation would be to either plan on using the Morning EMH, or the Evening EMH for the entirety of the trip. It is too tiring to do the Evening EMH, and then get up for the Morning EMH the next day. Also, do take note that A TON more attractions are open duirng the Evening EMH, than the Morning EMH.
