My husband, young adult son, and I rented 2 condos. If Island Park was a future destination for us (we always try different destinations,) I would absolutely rent with them again.
We stayed 4 nights and went to Yellowstone twice and Gardiner once. The drive to the park is reasonable and it keeps you out of the madness of the West Yellowstone commercial area that is before the park entrance.
The team in the front office is hospitable and kind. The appliances are all in good shape. Showers have great pressure and hot water. There is plenty of space and peace.
Island Springs has the best tap water I’ve had since the 80’s when I lived in a an artesian spring-fed neighborhood.
Both condos need carpet removal— there is some odor in them. However, it’s summer, so we enjoyed leaving the windows open the whole time we were there. It’s not luxe, but it’s clean, safe, and comfortable.
