Another thought: could the magic just be wearing off frequent travelers? I think about the first time I saw The Usual Suspects. My mind was blown and I had to see it a second time. Then I went with a friend and saw it a third time. It was pretty good. These days, I have no interest in seeing it again.
If I've seen all the Disney tricks and special touches, are they really going to be special to me anymore? If I'm seeing my daughter get called princess for the third trip in a row and being made paper flowers, is that high service or just what I expect? Honestly, I'm trying to resolve the negativity I see from so many veteran Disney folks with my own experiences as a new user.
To me, the things you mentioned are part of the Disney brand and I don't necessarily equate those with good service. For some that "pixie dust" is enough.
You also said in a PP that DCL gave you the same level of experience as the Four Seasons so it may have gone beyond the things you mentioned.
Please note, I'm not attempting to argue your feelings just engage in discussion from my perspective.
I will give some tangible examples of things I've experienced with Disney that for me created a lack of belief in their unrivaled service.
On two separate cruises I had to call housekeeping because my supposed to be freshly changed bed had grease stains and blood stains. No apology and it took well over an hour to change the beds. To me that's shoddy service.
On my 2nd DCL cruise I got out of the shower and grabbed a towel off the rack and it's a good thing I looked because (I wish I were making this up or exaggerating) it had a poop smear on it (yep I could smell it). Again no apology or any ownership from housekeeping of this mistake. To me this was just horrific and again should have been caught by "impeccable service" or at least handled much differently IMO. Not a situation where "eh, here's another towel" is appropriate.
I've had other experiences with incorrect orders in the dining room, inability to order from a different dining room, having to haggle with guest services over incorrect charges. None of this holds up to service above anyone and certainly falls below some standards.
In contrast, I once had to call housekeeping at the Four Seasons because they had forgotten to leave clean hand towels. I got a visit from the housekeeping manager who delivered the towels in about 3 minutes, a call from the hotel manager and when I returned to my room after dinner found a lovely box of chocolates with a note.
You may have very different opinions based on your experiences, but I'm not just hating on Disney lol. I wouldn't even care if Disney flat out said "you're paying a premium for us to slap Disney on it", which I believe is accurate. It just bristles me as I continue to experience spotty service yet hear ad nauseam about Disney unmatched service.
For me this has nothing to do with offerings being taken away. This is strictly based on customer service, which has some basic tenants Disney or not.
