We did EE at MK and AK in May and had no problem.....but if you want to know about summer, this is a completely different form of animal. We just returned last weekend after 11 days and EE was horrible at both MK and AK. We tried both and then avoided it like the plaque. Mind you, we are BIG EE fans and support it, but not in the summer. I posted on another thread that we tried EE at MK and it has packed. We then did MK on Wednesday and got more done in less time and had very little wait. But the biggest surprise we got was doing MK on Saturday morning. I've always avoided MK on Saturdays, but figured with the crowds we were encountering, this couldn't be any worse. Surprising it was the lightess crowd of any day we visited any park. Mind you that the night before was e-ticket and MK was open until 1:00 AM, so with that in mind it was a dream. We found AK was packed any and all mornings, but was much more doeable on non-EE days. In the fall we will go back to our routinue of EE-mornings.
