We were campground hosts at Chiso Basin CG at Big Bend from Apr to Aug 2014, and at Davis Mountains SP from Oct 2014 - Jan 2015.
Both places told me that Spring Break was their busiest time of year, with every reservation taken, and lines of people waiting for non-reserved campsites to empty each day.
We experienced that happen on Memorial Day weekend 2014 in the Basin CG.
I do NOT expect COVID restrictions to lift until late spring/ early summer for National Parks. For one thing, I'm seeing much fewer than normal volunteer positions open in federal campground locations. If they are not scheduling the volunteers, they won't have the staff to handle lifting restrictions.
The Hot Springs are closed IMHO because that tends to be a gathering place. Unless they post a ranger as a guard to monitor the number of people at the place. Over crowding there did cause some issues while we were at the park.
