The nearest 'real' town is Nampa. Nampa Hotel Directory - a directory of Nampa Hotels. The Shiloh in is ok, and pretty convenient.

If you want something fancier, Boise has some very nice hotels but you'll have to count on a 1 1/2 hour drive. The airport hotels are ok, and you can get to basecamp by the back roads in about a 70 minutes.

Another option for housing is an RV rental - search www.google.com for 'RV rentals Nampa Boise' for a list of rental places.
