This all comes back to declining levels of quality and service at WDW driven from the top down. This is a problem created by Disney management.
In the 1970s and 1980s, there was genuine concern for the WDW customer at the highest levels. There was a palpable attitude that the customer came first. However, there also was concern whether those high standards could be maintained as WDW grew. They knew it was going to be a challenge. They believed they needed to step up their game to handle the increasing crowds. They believed it was a time for a renewed investment in WDW's commitment to quality.
Instead, by the early 1990s, Eisner and Wells began pressuring WDW management to improve margins, eventually pushing out WDW's old-time leadership (who I call the Old Guard). Once Paul Pressler was put in charge of Parks & Resorts in 1998, WDW's decline was assured.
This does not mean that today's WDW stinks. It does mean that WDW has declined.
I would have graded WDW an A+ experience in the 1970s and 1980s. With all the exciting building going on through 1998, I'd even give this grade to that decade as well. I certainly don't recall seeing quality cuts back then, and I suspect that was because most of the initial cuts happened offstage or involved maintenance, which took time to take its toll. Even today, I'd give WDW a grade of a B or B+. WDW is still good but the corporate priority has shifted from "profits through quality" to just "profits", resulting in a lower grade.
Those of us who complain about today's WDW do not hate WDW. Quite the opposite. I suspect we love it at least as much as the apologists (a.k.a. pixie dusters), who seem to accept declining standards as part of the normal business cycle. We so called doom-and-gloomers simply know what WDW is capable of becoming once more, with the right leadership.
Even in the 1970s and 1980s, Guests could be demanding. However, Disney gave so much and, relative to today, charged so little that Guests overwhelmingly were grateful for the WDW experience. WDW was exceptional for its time exactly because customers were provided excellent service for relatively moderate prices. The WDW of the 1970s and 1980s did not operate like other companies of the 1970s and 1980s. The "Disney Difference" was real.
With prices being what they are today, customer expectations have been raised exactly at a time when WDW has lowered its standards. Today's CMs are dealing with more difficult customers, but that's because those CMs are being placed in more difficult situations by decisions made at corporate.
This is not a problem with WDW's Guests or Cast Members. Overwhelmingly, this is a problem created by Disney management.
