We stayed for one night at a Frontier Cabin (cabin 108). The cabin itself was actually nicer than we expected. The cabin seemed recently renovated and they were in the process of painting all the cabins on the outside. From our cabin you could see Old Faithful from the side window and it was only a 150 meter walk to get to the benches around the geyser. Couldn't believe we were this close!
Only minus was the bed, which was a double and that is on the small side for two people. But other than that, you can't beat the price for this location!
