How are mobility impaired guests doing since reopening?

We have 3 mobility impaired guests in our usual party, all of whom require scooters. One has respiratory issues, and obviously is not considering a trip at this time. The other two have no issues with breathing, but have things like hip transplants that prevent them from walking the parks. If you or someone in your party is in a similar situation, I would love to hear about your experiences. How is bus transportation working out? How about transfers into and out of of attractions? Any other new obstacles or surprisingly good accommodations you have seen?

Thanks in advance!
