Going to Vegas and want to save your money for the fun and not splurge on the hotel room? The Orleans is your place. Off-Strip so the rooms are cheap, the drinks are plentiful in the casino, and the crowd is... well, a bit like the casino in Swingers.
The free shuttle to the Barbary Coast on the Strip is handy so you don't need to rent a car if you're flying in as well.
Decent Cajun-ish restaurant, too.
