I read that the booking window for Housekeeping Camp begins 365/366 days prior to the date you wish to book. Is the "ordeal" similar to booking campsites? Specifically, a mad dash at whatever moment DNC opens, with every site vanishing within 2 minutes. I am hoping to book for a larger group and may require 3 sites for the same dates in July. This would be impossible with the campground reservation system, so I am putting my hopes on Housekeeping Camp. Any info would be appreciated, as always.
