Sin City Hostel
Time Out says
The lack of youth hostels in Vegas is easily explained by the fact that you can get a room in a Downtown casino for $30 or so. Still, despite its location in the Naked City neighborhood, the Sin City Hostel has built up a nice reputation. The dorms are relatively cozy, and there are also semi-private doubles. Amenities include free laundry facilities, an internet terminal and a jacuzzi pool. Guests must produce a student ID or proof of international travel at check-in.
