Beachcomber
$89-120. basic clean rooms, looked okay and was verified by someone at the National Hotel. Cute, didn't look terrible or anything. Tripadvisor.com doesn't love it but it sounds better than the others on this list.
Clay Hotel
was very cheap, $53-105, $24 for dorms. The dorms are rumored to be horrible, the hostel in general, but it hotel part seemed okay. You get what you pay for, a hostel in party city is bound to be scary I guess. At your own risk. Really charming location off Espanola Way. Not really close to the National, long walk or short cab ride. TripAdvisor reviews are promising. Nothing fancy but if you really need a place for under $100, go for it.
