I think it depends on when you are visiting. We tend to visit in the summer and school holidays like Thanksgiving week & Christmas. So, from our experience, the MK early EMH are awesome. One year we went at Christmas time and we did the early EMH and rode a ton of rides. However, it started at 7 am so, we had to get up at 5:45 am to get to the park in time. Anyways, we had family with us that were staying offsite so, they joined us after the hours were over and guess what we had to leave at 10 am because the place was PACKED. We rode two rides from 8 am to 10 am. I'm sure it was because it was Christmas week. However, if EMH are in the evening I avoid that park like a plague. It just isn't worth it for us. Usually it is crowded from around noon until the start of EMH and then, after that it is better but then, you spent the day suffering the crowds. So, not worth it.
