WDW quality has run several cycles in those 42 years - and it is now about as low as I can remember. Food quality in both the QS and table service restaurants is down, and many of the "signatures" should be re-categorized - most are little better than a hospital ER where the goal is to get you in and out as fast as humanly possible while separating you from as much cash as they can.
Park cleanliness is just plain putrid compared to the '70s.
Disney now treats guests the way most doctor's offices treat patients - your time has no value.
I could not believe how things have deteriorated over just the last 3-4 years. When rode Buzz Lightyear earlier this month, the thing that hit me when I entered the building was "wow, why is this place so dirty?". The entire queue area, and all the ride cars, need a gigantic scrubbing and refresh. Badly. And many other areas of the parks are in the same condition.
We were there for 9 days and thus ate counter service meals quite often, at least a couple times a day most days. I can count on ONE HAND the number of times I did not have to clean off a table. They didn't have people doing any cleaning - in order for my family to sit down and eat, I had to remove trash from tables and use napkins to wipe food and debris away from both tabletops and chairs. I remember standing in line for 20+ minutes to get food from the Patisserie in France, going to find a table, and everything was filthy. Tables looked like many families had eaten at them without anyone wiping them down. Sticky and spilled food and drink dried on top of them. It was really gross. And this happened over and over at counter places.
One afternoon we had a 4pm reservation at Rose and Crown. Unfortunately for us, they seated us outside. The reason I say unfortunately is because for whatever reason, they were convinced that people sitting outside would try to stay 5 hours for the fireworks (again, this was 4pm in the afternoon). We were informed, as we sat and were handed menus, that there was to be no lingering and we needed to eat and leave as there were people waiting for our table; the waitress repeated this multiple times during our meal, as did the person who delivered our food. And we were only there 45 minutes, we ordered our food and ate it quickly because the seagulls kept trying to land on the table. All in all it was a miserable dining experience that I paid $100 for. If I ever go back - and even if I return to WDW, I don't know if I'll ever go to Rose and Crown again - I'll be sure to ask for a table inside so perhaps I can eat my meal without being treated like a deadbeat.
Another day we had a 1pm Tusker House ADR. We checked in at 12:55 and waited a full hour before we were given a table. No apologies, nothing but "oh we had a computer glitch". When we finally sat down, it took forever to even get drinks. Half the party was done eating before beverages finally showed up.
Our room keys didn't work, and we waited in line over an hour to get them fixed.
And those are just a few of so many bad experiences this last trip, the whole MDE thing was actually just a small part of it.
No, they aren't getting our money anymore unless and until they fix a whole lot of things.
