Just got back from a 4 day Disneyworld trip. We visited Epcot, Hollywood Studios and Magic Kingdom (2 days). I have to say, Disney is doing everything they can to make everyone feel safe. Even with the rides less than 1/3 full and no Fast Passes (only virtual queue for Star Wars - Rise of The Resistance), there wasn’t a ride with a wait of more than 20min. The lines were all marked so you would stand distanced from the next group, and it was super organized. We still got to eat at all of our favorite places (sit down restaurants) in the parks. There were hand sanitizer stations at the entrance and exits of every ride, restaurant, store, and building, so it became a norm for people to use it often as it was right in front of them and super convenient.
I was hesitant at first because of the mask requirement and the heat but you have opportunities to take breaks (relaxation stations or eating/drinking while stationary). I almost prefer the parks like this to be honest. We booked another trip in the near future, and can’t wait to visit again!
I’d be more than happy to help answer any questions y’all may have about Disneyworld and the experience. As a 10yr Disneyland Annual Passholder, I hope Disneyland can re-open again soon - Downtown Disney capacity crowds is already showing people’s angst, as I know the local annual passholders are more than ready!
