We usually do the evening EMH. Since we came from CA with the 3 hr. time difference I just can't wake up DD6 to go early.
Before I had my DD, my DM and I would do the a.m. ones and they were great. We always have park hopper so once the parks get busy, we'd leave and go back to hotel for a break or to another park.
We LOVE the EMH at Epcot. It's so cool to stay until midnight.
That being said, in January when we were there, TT was down for maintenance and the line for Soarin' was huge! We didn't really care since we have the original here and have ridden it many times. MS line was short. Also, since we're dealing with the time change, staying later is not as big of a problem for us as it may be for others.
As far as AK goes, I'm not sure if we'll do evening EMH again. We got there during the Jungle Jammin' parade and we couldn't get to Safari ride-we were stopped about 10' from entrance-so frustrating. We were able to get in line as soon as parade ended, however, since safari ride closed at 5 p.m. we only got to ride once. We were hoping to ride several times. In the past, when AK was open later, we really enjoyed the ride early evening/sunset.
If we do it next time, we'll make sure we get there
before the parade so we're not blocked.
We have never been there during times of huge crowds. We've never done July or August. Both times in June we thought the crowd levels were manageable. Sept is always great!
We will definitely be doing EMH evenings next trip.
I've already looked at the calendar and scheduled some of our meals based on doing EMH.
Hope this helps.
