Ron,
We were just there; and although there was a supposed drop in the crowds, MK was still the most crowded park--and packed on the weekends.
On the four days we went to MK on EE, many of the rides that are part of the EE program had a 30+ minute line before noon (Pooh, Dumbo, Peter Pan, Buzz, Astro Orbiter, etc.) Those are awful long times for small children to wait--so that 1 1/2 hours we get for EE with limited access really count (and it doesn't hurt that it is cooler in the early mornings also).
Also, with the park hour cutbacks, you will find that as parks open later in the morning, they will be more crowded from the start. And as the parks close earlier, the parks will stay crowded until close. There won't be that hour or two of lower crowds that the early birds or night owls used to enjoy.
I also found that at the other parks with EE, there were only a few attactions open, and many of those had fast passes, so EE was not as important. But, I think for many of us with small children, EE really helps us enjoy MK and was very much a part of our vacations plans.
I will be interested in hearing reports from families who used to do EE (especially at MK); and how the loss of EE and E nights affected their trips.
