Baker's Hole is one of our favorites too but just to suggest another option although this would add some driving.....Red Rock Canyon in Idaho(about 15-17 miles to the West Entrance to YSNP). Great Campground off the beaten path near Henry's Lake. I just got an E-mail from them indicating a change in ownership and many upgrades they've done. Might be worth a look.
We stayed there years ago and had a great time and the drive wasn't all that bad!
Henry's Lake State Park is nice too with most site having water and electricity and a few with sewer too. Spacious between sites and a view of the lake from every site. We were there the Fall of 2017 and Moose were in the willows below the CG every day.
