My wife and I stayed in the "cliff dwelling" style units for 5 nights, and we had a wonderful experience. Because these units are in high demand, we split our trip between two units - 8 and 7. The even numbered units are in at a higher elevation than the odd numbered units. Both the even and odd rows are quite private - no one can see into another unit, really, from inside their own unit. From the roof of any unit you can barely see the roof of any other units, giving you good privacy while grilling/hot tubbing.
The huge benefit of the cliff dwellings is that you can grill your own dinners on the roof, stargaze up there, and hop in the hot tub after a long day of hiking. The inside of the structure is cozy and the hosts have provided all of the supplies you could need to operate the grill. We bought groceries and cooked for ourselves, which is a nice way you can save money when staying here.
The resort is conveniently only a 20 minute drive from Zion National Park, which gives you the added bonus of being separated from the crowds in Springdale during the busy season. This also means less road noise / light pollution. The nearby towns do have a bit of light pollution but if you live in the city like us, you'll be very pleased with the clarity of the night sky here.
The white bison themselves are a great cherry on top here. As of now there are a few young bison and we quite enjoyed watching them eat for a while one night.
Lastly, these units face south meaning you can catch the sunrise AND sunset from inside or on your roof - and I'd recommend catching every one if you can.
We'll be back. It was a great experience.
