I tried to stay in Moab as I was passing through that weekend. My wife and I literally just parked, ate lunch, and stared at all of the people.
We were looking for a room so we could shower and sleep in a soft bed, the cheapest we could find was the Motel 6 at around $150. It seemed to me to be much busier then I have ever seen it, even on jeep weekend. I could imagine the lines of people on the slickrock as well as the groups walking their bikes along the trail because they underestimated the terrain.
It is a tough issue. It is really nice to see the businesses doing so well and so many people enjoying that area. On the other hand, it sucks that everything is so crowded. I say let them have Arches, Zion, Moab, Bryce, Deadhorse and Island in the Sky. I'll keep the Maze, the Swells, the Waterpocket Fold.
