We checked out Yellowstone Holiday last fall (on their last open day of the year), and liked it, especially the newer eastern section, though it's spendy because much of it is right on the water and it is a popular place, hard to get a spot. I imagine Stan will go down Hwy 20, following the Henry's Fork south. We enjoy the back country route say from Ashton east and south via Driggs, or hwy 33 east out of Sugar City. Of course I have to put in a plug here for beautiful Aspen Acres Golf and RV Park 7-8 miles southeast of Ashton.
We haven't been across the Victor/Jackson route, but in an RV detouring south via Alpine, WY, Palisades Reservoir, and Swan Valley was an okay route. If he is only taking his toad across hwy 33/22 to explore Teton NP and Jackson daily, he should be fine, right Karl?
