Ho-Chunk Gaming, Wisconsin Dells
This is so Vegas, with slots 24/7, blackjack, five restaurants, luxury hotel accommodations on par with premier Wisconsin Dells hotels, talented musicians and comedians performing, a fitness and aquatic center and a convention center. A large bingo hall seats 500.
Mind you, this is just a partial list of the Wisconsin Dells attractions that are available after the sun goes down. Ask locals where they like to go for entertainment and you're bound to get an expanded inventory of recommendations, like live music at area clubs and pubs, sunset dinner cruises, or the old-timey outdoor drive-in theater.
