Just a note about EMH.
The last time we were at Disney we decided to try EMH at the Magic Kingdom. We figured there'd be less crouds, more fun, etc... Wow were we wrong. When the part closed it just got busier and busier. I couldn't believe it. The crowds and the lines were massive. Way worse then earlier that day.
I didn't and I still don't understand that. I would have figured that half the crowd would have left leaving just the resort guests in the park. We stayed for about 45 minutes (the time it took us to walk from one side of the park to the other in the sea of people). It was nuts.
Perhaps we just caught it on a "bad" night but wow were we surprised. Way too crowded for our little ones.
Hope your experience is much different.
