If you are doing EMH, Go for the EMH. Have park hoppers. Do not go to that park for the regular hours. EVERYBODY ELSE DOES TOO, then stays for the EMH. The best idea is to hit the morning EMH, and plan to get out and go somewhere else about an hour or two after the normal hours begin. The crowds get really busy from normal business and EMH. Night times are MUCH WORSE. If you go to EMH nights, go the last hour of regular hours or wait til EMH starts. Go to another park til then. Lots of people use EMH days to stay at one park the whole day. So EMH days can sometimes double the ammount of people in a park for that day during regular hours. Also, nights when there is MNSSHP or MVMCP are REALLY BUSY at MK. Even though people think it will be less crowded because of the shorter hours, many people go there then hop to another park. Plus Special Event tickets open up around 4 or so. That is when guests get there. Plus many of them just use the whole day at MK anyways. So go for EMH, but don't use that park for the normal park hours. It will be VERY busy. EMH nights are VERY DEAD after the first hour or so. Most attractions will be walk-ons. Except Sorin.
