AndrewC: Thanks for the report. Too bad the trip turned out so differently than planned. Just remember this: The mountain will always be there, so you can try it again.
Next time, maybe spend a night at Horseshoe Meadows to get a head start on the acclimatization.
Edit, for Publius below: Note that AndrewC's group experienced some AMS issues. For people like that, staying overnight at 10k can give them a little more acclimatization advantage, and maybe stave off the symptoms when they do the hike.
