Replying to Accommodations for minors in Tahoe

Living 4 hours away, day trips aren't the best option for me, and being 17 years old, it has proven to be hard to find a cheap place to crash for the night when I want to come up for the weekend. Does anyone know of any cheap places to stay that allow unaccompanied minors? I have the Tahoe Local pass and generally ski at Northstar, but would basically be happy to find someplace to stay anywhere, North or South Lake. Thanks!
