We done the same thing on our trip of August-September. We've read all the postd\\s saying to shun the parks with EMH's but tend to find out for ourselves. Granted at the opening of EMH it tends to be rushed and crowded, don't go at the start, after the first hour the parks seem to wean out and by the end there are hardly any folks left. We generally like the MK and staying in the park after mid-night is awesome, makes for a long day but we hit a park that day till around 1 pm, take our pool resort break, do some shopping and relaxing, knowing we're going back kind a late and staying long. Never avoid a park with EMH's, try it yourself, if its not to your liking you can just leave, if you don't go, you'll never know!
