"Sleeping" on the summit. An interesting and difficult goal in its own right. Could be a miserable night. How much acclimatization did you have in mind? I know, I am probably focussing in the least interesting aspect of your post. I would like to sleep on top of Whitney one of these days, but my plans to do so after multiday high altitude hikes (where I was acclimatized for altitude) have been foiled twice by weather.
