We also stayed at Ruby's at the entrance to Bryce two years ago. Nice campground and very easy access to Bryce. When entering and leaving Zion, make sure you use the west side through Hurricane. The east entrance has a mile and a half tunnel that requires a permit and has low, arched ceiling. You have to ride the center line through the tunnel after it is shut down for one way traffic. Also, no combination of tow/toad over 50' long is allowed.
