You asked and I'm in a mood so ...
I don't like the wedding reception party thing they do at the pools every afternoon. I don't want loud pop music and hula hoop games and a blaring microphone. I want to listen to resort-appropriate music while I consume my overpriced beverage.
It annoys me that when Disney adds new 'lands', they build one good ride and one throwaway (Mine Train/LittleMermaid, Slinky/AlienSS, FOP/dumb boat ride, etc). Is it really a 'land' if it only has 1 good ride, a store, and a QS? Even the MF ride itself is pretty weak even though the set is cool.
I LOVE star wars, so it always annoys me when I visit GE that the whole place is a made-up storyline instead of something drawn from one of the movies. Nothing is recognizable until you get to the MF ride. It's what another company would build if they wanted something to look like Star Wars but not get sued for copyright infringement.
Also annoying -- when Disney puts a new thing in place of an old thing instead of just building something new. I get why Ellen's EA had to go, but why didn't they just update the Great Movie Ride and put MMRR someplace else? Why did we lose the muppets for the monsters ride? Why is that decrepit Figment ride still there but Maelstrom is gone? Why did we lose the original Soarin' movie????
Related ... the sad state of tomorrowland, the imagination pavilion, Morocco, Stitch's GE, etc. Why build new lands before fixing what's already there?
Also related ... the sad state of the Boardwalk area. Used to be the best place to spend an evening. Again, why build new bars in the parks and leave gaping holes on the Boardwalk?
Why do I have to make park reservations? This feels like the leftover '6 feet apart' signs I see sometimes from during covid.
Having to have my %$*@&!!!! phone out all the time. Related ... having to walk around people [like me] with their eyes glued to their phones.
The livestreamers in the parks. I wish this was banned except for special events (first day of a festival, opening party nights, etc).
I hate how complicated it is now when you try to explain it to people. We used to invite friends and family to join us all the time and all we needed to discuss was dining reservations (which is a normal thing IRL). Now, by the time I explain all the changes and iterations of LL's etc etc ... they kinda lose interest. We always used to travel with people but it's hard to get the casual visitor excited about WDW when it's so complicated (which IMO also makes it feel nickel-and-dimey).
Totally my own issue, but I get annoyed with myself at all the things I miss because I've been a member too long -- room service at BC, free FP and MB and ME, WL flag family, tours of resorts, Morocco, actual sports items in the shop in England and World cup stuff during WC tournaments, merchandise (esp in epcot) that wasn't IP based, rides that weren't constantly down (esp new rides -- I've still never been on Tiana even though I waited on line twice, and the last two times I went on Rise they had us enter through the stormtrooper room even though we'd paid $25 for the LL), etc etc etc.
Bonus DVC Pet Peeve -- Why is it so hard to look at the 'accounting' of my points and figure out which points I've used for what? DVC's IT and structure seems unnecessarily complicated. I usually hate AI bots on websites, but I'd like one on DVC's site so I could ask things like 'Are my borrowed points used on X reservation or Y?' or 'If I cancel this reservation, could I bank all of the points into next year?' etc.
Man, I'm quite peevey lol.
