We were just in WDW in the first week of June. My older DD was especially disappointed in the hours. She loves spending late nights at EMH, especially at MK. Closing down parks is one of her main Disney joys. Sure, AK was open until 1:00 am on weekdays, but it was two rides (one of which younger DD is too short for), and the wait times were insane. If we'd had EMH at MK, we would have been able to ride a number of attractions. Instead, we watched the drum show in Pandora three times. At the very end of the night, we hopped in line and did the River Journey, while the older kids did FoP. Luckily, they opened EE late on the weekends, so DD and friend were able to ride it 12 times in row. That was their idea of a great time. Pandora is beautiful at night, but you can only look at the scenery for so long. Kids want to, you know, DO stuff. And having only one ride with 60+ minute waits available to younger DD made her decidedly less than enthusiastic about going back. We could have gone back for additional nights at Pandora, but we ended up going back to swim and then relax in the room. Us at theme parks at night=us spending money. Us in the pool=$0 for Disney.
For me, longer nighttime hours are crucial. I am extremely fair and I burn badly. Reapplying sunscreen every hour and baking in the heat and humidity is misery to me. Being out in the parks after dark is so much more enjoyable. I sent an email to Disney last year regarding July 3rd hours, as the original calendar had a 10:00 pm close. The hours ended up being until 1:00, and 3:00 am with EMH. We stayed until the last ride closed, and it was fantastic. I'm not saying that my email made them change their minds, but the more feedback they get, the more inclined they may be to make changes.
We've had APs the past two years. We own DVC. We love Disney. But when they make a change that has a negative impact on my family's vacations, I'm going to send them feedback. I don't think that makes me whiny or entitled, and I don't think the others who've expressed their displeasure about these changes are whiny either.
