personally its nothing special, to me it felt like a western themed travelodge. the props are cool, and some of them themeing is neat, but the buildings are easy to get lost around and its expensive. i prefered the holiday inn much nicer and fanicer and cheaper.
that said the abillity to get to the parks on foot and not wait for a bus is really a big plus (except when youre tired.)
It's the weakest and cheapest of all the hotels, I think Cheyenne adds that bit extra that Santa Fé lacks. When you get a room at Cheyenne at the side that's closest to the park it's an excellent option.
