It is very difficult not to have people in close proximity indoors or outdoors at Walt Disney World right now. This is based on our last six days in the parks. It is normal Disney crowd levels this time of year and zero social distancing. Just be aware of that. Then it comes down to your comfort level and risk tolerance for the kiddos
ROTR is probably one of the better for social distancing, but there are queues where people will be on your back most likely and there are some enclosed spaces with people but that is pretty much like every ride at Disney right now. Also, it’s not a given that you will get a Boarding group for ROTR. Make sure you research how to get one. They literally disappear in two seconds at 7 AM the morning of your HS day. There is a second chance at 1 PM if you have already entered Hollywood studios at some point that day
my tip is to go into the AT AT screen on the
MDE app and start refreshing two seconds before 7 AM and as soon as the join button shows up hit it and then hit join on the next screen and the next one as soon as possible
