We were at Zion River last late Sept. A little pricy, but a very, very well maintained CG. WiFi a bit spotty, but aren't all CGs? They host various activities, included a weekly wine and cheese party. Best bet is to drive into Springdale, park along the main road, and catch the shuttle bus into Zion. Parking in Zion is very hard to find at peak times. We did find that around/after "dinner hour" that the parking at the visitor center opened up a lot! We were there 4 nights.
We stayed at the Cannonville KOA for Bryce. About 1/2 hr drive back to Bryce, but a good base for some Grand Staircase and Kodachrome Park explorations, also. We did 2 days in Bryce, a GSE slot canyon hike, and a day at Kodachrome, which seemed about right. In late Sept. it was wide open for space. Ruby's was busier, but also appeared to have lots of openings. Looked acceptable also from the drive bys we did.
