I always do the EMH (when it was called early entry) when I go to WDW. I have not been when there is evening one's just when it was in the mornings. We swear by it. When I went with my sister and her family in 2004, we got all of Fantasyland (some attractions more than once), as well as most of Tomorrowland done before the gates opened. It was more of a relaxed feeling, rather than rushing through the attractions. I still do EMH even when I go solo. You just get so much more done. Also, as I'm there solo, it also allows me to take my time and really take in the parks, such as strolling down Main Street (rather than running) admiring the windows on the upper floors. At EPCOT, being able to wander around while it's still quiet. At Animal Kingdom, taking my time and walking all the way around the Tree of Life. Usually I can get done all the musts on my list during EMH and shortly after that, then will head back to my resort after lunch, take a break, then head to a different park later that day. It helps break up the day.
