We were there from 9/25-9/29 so I'll share a few thoughts. I won't comment on masks, that topic has been covered ad nauseum.
Our flight got in super early, rented a car and headed straight for KSC. We had free return tickets from our trip last year when over half of the stuff was closed so that's the only reason we went back. Did a
Walmart stop for a few essentials, then checked into ASMovies. Drove to Wilderness Lodge for dinner at WCC that night and returned car to CCC early on the 26th. Enterprise shuttle took us to GF where we hopped on the monorail to MK. One note, I told them at check in we would only have the car for one night, but on day 3 noticed we had been charged 3 nights. Went to front desk and had the 2 nights of charges taken off. Well, on the last morning going over my statement I saw I was once again charged for parking. Back to front desk and they took that off, plus the first night for the inconvenience. So just note, if you don't have a car for the full length of stay, check your charges!
MK was great, longest wait was for Jungle Cruise, we had lunch at Skipper Canteen right after so that was a nice break. I found taking a long lunch break around 1 re-energized us to head back into the heat. We did almost every attraction at least once and all the mountains at least twice. Went to BB the next day, but I've already posted about that.
Last full day we went to Epcot, we only did 2 park days this trip and if I could do it over, I'd have went to DHS. I LOVE F&W, but it was just really lacking this year. Not the food and wine offerings, but just the overall atmosphere. No entertainment in any of the pavilions, it was just blah. Future world is a disaster and the barges are ugly. Don't get me wrong, I still love Epcot but it just wasn't the same. Also, being waited on by "Becky from Nebraska" in Mexico or Japan was just weird. Saw the last fireworks show before Harmonius debuted the next day. We entered through the IG for EE and were among maybe a dozen other guests walking around WS which was such an odd feeling! Got a few pics with no one in them which is rare!
CMs were mostly awesome, there was one in MK at the pretzel stand who wouldn't look up from her phone, I finally asked if she was open, she grunted not yet (it was 5 min til opening). There was one working at Peter Pan who had the same name as a little girl in line, so she gave her a big hug. Made me realize, guests can be all up in the CMs faces in lines, etc. but Mickey still can't pose for photos with us. Had a late breakfast at Topolino's our last day which was excellent, but the characters just kind of parade through, you have to be quick with your camera and they don't come close to the tables. A lot of money for a subpar character experience. I feel like Disney is definitely picking and choosing on how to use the Covid card on experiences going forward, no consistency at all.
ETA: Totally forgot to mention this! I know that service dogs are allowed at WDW and we saw a few, but I'm pretty sure little purse dogs do not qualify! We were in the pre-show area of Laugh Floor and there was this couple with a shoulder bag with a tiny little dog inside. How did they manage to get that snuck into the park??
