Technically I prefer singletrack, see Winter Park . I also liked the Gold Bar Rim Trail, a good mix of slickrock and sandy tracks. I would have liked to do more of the real technical stuff, but we didn't have time.
Nightlife is fairly good as it's a stopping off point for coach tours.
If you're in the area don't forget to do the National Parks, Arches and better, Canyonlands. The slickrock bike track is world famous and rightly so. This is not an easy route and don't be fooled by it's apparent short length - it's a technical and physical challenge. See the map below for route. If you fancy more, you can always try some of the spur rides.
