I think your missing the original posters point, its not a missing towel he is complaining about. The bus rides he described is horrible and combine that with the other stuff. The problems with his room you expect with a $49./ night room. These thing don't happen in a well maintained resort. People need to check the rooms for operations and comfort, not wait for the guest to call and say something is broken.
I too am one of the sour pusses you talk about, I was very happy at Disney for years, I went every year from 88 to 2000 and got an AP from 2000 to 2015 in which I visited 20 days a year. I loved it, even visiting that often, they managed to sour me. My wife and I just enjoyed being there, we rode very few rides, ate in the restaurants and just hung out.
When they changed and added the bands for entry and FP it really flipped me. Every time I tried to enter the park, the CM would say to touch the band to the Mickey and I asked with a smile "do you need my ticket and ID" and every time they said 'oh no', yet every time they ended up asking for it. I made a ton of trips to guest services to no avail(even gave me a new band). The one time I wanted FP, I made them for the 3 of us for a couple rides and all went well on the first ride, then the 2nd ride my wife and kid got on, but they had no FP for my band. During the same time I had a Disney rewards card with 80+ dollars on it and bought the kid a slushy that wiped out the $80, good thing the CM saw it, it was a computer error, she charged me correctly, it took a manager to come straighten in out (over 1/2hr).
Added to just a few of my encounters above, the with all degradation of service and increase in fares, I have just lost interest. If you could tell me that the next time I go, it will be a reset to the 2000 quality/service, even with today's prices, I would be there in a heartbeat.
I am sure the CM's have it rough and people probably pound them with unreasonable demands, so that adds to decline.
Maybe I am seeing it wrong, I honestly cannot tell you within $10,000 dollars, how much I have spent at Disney over the last 4 decades, heck I can't tell you how many times I have spent over $200 for dinner. Perhaps I cheap out, so I am not getting service that I think i should. I have over the years never complained once to Disney or a CM or at any place I frequent for that matter, my answer is, I just don't go back.
