Re advice on where to stay:

We did Labor day last year, spent two nights at a reserved site in Onion Valley campground to acclimate. Great acclimitizing hikes near the Onion Valley trailhead -- can go up to one of several lakes, or even all the way to Kearsarge Pass. Then into Lone Pine to pick up your permits, maybe to the Hostel for a last shower, Subway for a sandwich, and onto the trail!

This year, I'll be up for an overnighter on July 23 weekend (yay!). May do an acclimitizing night at Lone Pine Lake on the way up to Trail Camp...
