For magical express--the trip from the airport on 7/25 felt extremely safe, with them assigning seats--loading from the back, and keeping 2 rows empty between groups. It sounds like the trip from the airport is still operating that way. I think there was going to be 4 resort stops, and we only waited 15 min for a bus at 5:45pm.
Coming home on 8/8 though felt like a free for all. We had to ask guest services for the printout to know when our bus would be at AKV Kidani--2pm (We had a split stay, so not sure if that affected it...I had to do 2 DME reservations initially for each leg of the trip.). A DME bus was dropping his last group off at 1:56, and didn't think he was our bus...turns out he was, so he told us to sit anywhere...we double checked...yep anywhere. And his mask kept slipping off his nose. Next he picked up at Jambo, 2 groups got on, and they social distanced from us on their own. Next he went to Pop, where they were sending tons of buses for a huge group (part of the 92 member family reunion we saw in the parks previous days.) Their bus was supposed to be 2:35pm, most didn't have their luggage yet. About half the big group got on our bus, eventually, but didn't social distance despite plenty of seats being available, and they were extremely lax with mask wearing--some having it off completely. We were waiting at Pop for that group for so long, we feared we'd miss our flight with having to self check luggage and security--thankfully, luggage and security were quick..like 5 minutes to get through security...unheard of for us at MCO. We flew Southwest and there were empty gates to spread out at, and only 35 people on our flight home. So it all ended well, but we weren't happy with DME on the way home... probably depends on the bus driver...from the radio, it sounded like they were still trying to figure out the bus routes back to the airport... hopefully they get that figured out soon.
