OK, one more attempt at reason. LV has a hostel--during the time frame you will be there, $17 S-Th and $22 F-S for a bed in the six bed dorm. It is in the 1300 block of Fremont, so guessing that is a bad part of town, but it's still gotta be better than any idea Larry David has come up with yet.

Oh, nevermind. Read in their FAQ you have to be a non-US citizen, or have an out-of-state college id. Since taking even one class at a community college gets you an id, well...possibilities there to easily get a legit card. For anyone enrolled in college this past spring, however, might be worth looking into. Any non-American just has to show passport.
Gonna go ahead and post the info. Figure every cheapie on the board is reading this thread.
