Welcome to Mousebuzz! September is a less busy time, so hopefully you don’t run into any serious crowds. There are a lot of different opinions on EMH, especially in the morning, here is my 2 cents worth: Do MK on Thursday and use the EMH. The parks are less crowded when they first open, and if you get there just before/right at opening you will be able to do the rides and hop to another park if MK is getting crowded in the early afternoon. When entering MK, many people go straight towards the castle and them into tomorrowland area. If you do the park in clockwise fashion, you can sometimes avoid this mass of people. Take the bridge and go through Adventureland and work your way around you will be able to do those rides with very little wait.
