Our Tahoe trips were a pretty good value...but we had 12-16 guys and a very experienced organizer in our group so I'm sure that helped. Two guys would probably be looking at a hotel; we were booking large condos that kept the price per person down. I'm almost 100% sure I spent more on beer than on lodging on those trips.
And the town was awesome, primarily because during March Madness I *will* bet on anything that moves.

Nightlife was, of course, quite good as well.
