We quit trying to stay east of the Teton Range or south and east of Yellowstone years ago. It got too busy, so we changed to W. Yellowstone for the Park visits, then move to Victor ID for the Teton visits. W Yellowstone is right at the west entrance and it's 24mi from Victor to Jackson. I know for the majority of people it's a first time experience, but we've had to adapt since the days we could arrive and stay about anywhere without reservations...yes, we're talking '60s to early '90s.
