I see your concern. Would be for me also. To see Yellowstone you will need to walk on narrow boardwalks. Almost impossible to keep 6' distance. Some groups will walk side by side and will not move over.
If you do go don't try to pull a camper into the north-east entrance.
Shame all this covid stuff is going on. Had a trip I would like to make but not too sure. My age I'm quickly coming to the end of my towing days.
