Honestly, we only travel in the off season. And even with good park planning, the days with walk-on rides are few and far between. Disney is one step ahead, offering free dining during these times to be sure and still fill the parks. I think all it has done is shift traffic from higher crowd times to the previously low crowd times.
Yes, we'd always go in September (once in Nov.). My DH and I started going to Disney with our honeymoon in '95. During those heady, early years of our Disney addiction, I seem to recall that MK was only open late with fireworks during our stay on the Sunday night we'd arrive. We'd be sure to be on the landing at the Contemporary (before they put the seating there) to watch them. The rest of the stay, MK closed at 7:00 p.m., I believe, so we ended every night at Epcot. Even with those tight hours, we were able to do everything at a nice pace, reasonable crowds and wait times, and I'll bet Disney was still turning a nice profit.

But, they've figured they can offer "free" dining (which served to further decline the food quality), lure huge tour groups, etc., so now there are
lower-crowd times, but not anywhere like previous years. I think the choice has been made for quantity over quality. BTW, they had a Fall Fantasy package at that time that included free daily breakfast (you could even do character ones each day, if you liked!), a small room discount and a coupon book.
We still arrive on Sunday, so we always take advantage of those MK EMH's (and spend money in the park). I guarantee we won't be wasting a ticket day to hit the parks after arrival without the EMH's. And, that doesn't mean we'll add a day on the other end. That means one less day in the parks.
And, it is the small touches that mean so much to those of us here. To us, Disney is so much more than a theme park, but to those who are clearly Disney's new target market, it is "just" a nice vacation destination to check off their list, etc.
We're still debating this year's trip, but we've already discussed that if we go, we must approach it with a different mind-set and stop expecting a Disney that is no more. A Disney trip is a lot of work, and unfortunately for us, at this point, it's almost not worth the trouble. Trust me, once you get out of the habit of going every year, it's not so hard to imagine not going, if that makes sense.
