WDW is always looking to cut opex. One way to do so is to reduce operating hours.
On a few threads, people have commented along the lines of "I went last year for Spring Break and MK was open till 1 AM; this year it was only open to 11 PM." It appears this trend continues this summer, despite reports of increased crowds.
We've already seen evening EMH cut back from 3 to 2 hours. I did not read a storm of protest which corporate Disney will likely interpret as a sign that even further cutbacks are possible. For now, I think morning EMH might be safe. Even Uni and my local Six Flags offer early opening and we all know WDW of late has been striving to achieve the level of
excellence of Six Flags!
As far as onsite perks, let's see what happens with MyMagic+.
