In reply to The Ivanator:
We stayed at Camping Marmolada recently, which was decent with hot showers. The ground doesn't lend itself too well to tent pegs though!
We climbed the Messner routes on the 2nd Sella Tower which was excellent with good quality rock. It's about HVS 4c, but reasonably sustained at that and some decent runouts. Good holds but I wouldn't want to puch my grade on it. We also did the tissi route on the 1st tower which I didn't think was that great, maybe 1 star.
I wouldn't bother with pegs on anything remotely popular. There are embarrassing numbers of in situ ones of varying quality, on the whole surprisingly good (but we didn't test them!) Rack wise a set and a half of nuts and 6-8 cams up to size 3 friend/gold camelot was plenty. A couple of small cams isn't a bad idea.
Wild camping isn't officially allowed, but we saw quite a few dossing in the numerous lay bys on the way up to the pass. Most didn't look like climbers.
The guidebook times we found fairly accurate, but you need to move together on the easy pitches. If you pitched everything you'd add a lot of time.
