We stayed for 3 nights in the Cave Dwelling unit. The site was very clean, they check on the hot tubs daily to make sure the water levels are correct and in good order. Staff was very quick to help with any issues. This was a very comfortable stay and close to the south entrance of Zion National Park. The only downfall was the view - there was construction going on across from the property but we would definitely stay here again.
We spent 3 nights at this campsite and it is kept very clean, the amenities are well maintained. There is a beautiful view and very little light polution for star gazing. However if you plan on camping in a tent - the sites are very close to eachother with no visual privacy, the ground is very rocky and the tent pads provided are small (I could not fit my bell tent). The gorge act like a wind tunnel so it is extra windy.
I would highly recommend this spot for RVs and Travel Trailers but for tents it's not super comfortable.
