I don't know if you folks from out of town are hoping to rough it, but the Hyatt is directly behind the museum trail entrance. If you're wondering where to stay, if they have openings, they're certainly perfectly located.
I don't really enjoy camping near as much if I can't sit around a campfire and swap stories of wild adventures in the wilderness, and with the dry conditions, fire restrictions are probably in place. So, if you can't beat 'em, join 'em. I stayed out there last summer, and really enjoyed coming back down to a comfortable pool, a soft bed, and some delicious Mexican food at Las Casuelas.
Just a thought. Hope to see you on the trail.
