I totally forgot to mention ride seating from my visit last week...
A party seated in every row: LWTL (with plastic between rows), Soarin (with seat skipped/plexiglass between parties in same vehicle), BTMRR, Safari (plastic between rows, CM driver = no mask while talking, which surprised me), EE.
A party in each car: SE, Pooh (we were a party of 2 and had our own car - no other party in 2nd seat of car), Nemo, UTS, HM.
Rows skipped between parties in same vehicle: Dino
I was totally okay with this... until on UTS, I realized I was within spitting distance of the man in the car next to me when we were side-by-side, and on Soarin, when I was in and end seat and realized once we were in the air, I was maybe 2' from the person in the next vehicle's end seat. Nobody took their masks off, so I wasn't worried, exactly - just aware of the proximity, I guess.
I mostly find it mentally problematic that WDW felt more distance was necessary before, and now thinks they can stuff more people in at closer distances - but hasn't mentioned the why behind it. Did the science say we now know that distance isn't necessary? Or are we the proverbial toads in the slowly heating pot as WDW increases capacity to get more $$ flowing through?
