Do non-Disney Resort guests stand behind the rope until 8am while CM's let guests with Disney Resort room keys go through?
Sorry, I was in a hurry and did not express my thought very well. The conventional wisdom on touring strategy says that you should always avoid the EMH park (or go only for EMH) - because after the "extra" hour it will quickly become more crowded than any other park that day. Normally, the EMH park changes from day to day. But on a few special weeks (our experience was at Christmas) MK may be the EMH park every day for a full week.
What I was trying to say was that we went to the EMH park, but arrived at the regular opening time. There was no second rope drop, we just timed it as if there was going to be an 8:00am rope drop, arriving at about 7:45. In our experience there was no sudden increase in crowd size - partly because it was so early and partly because it was just one of serveral consecutive EMH days at the same park. In other words, it did not work like an ordinary EMH day even though it was an EMH day.
