Introduced in a flurry of expansion, underwater apartments never became widely popular due to their persistent algae infestations, plastic-castle décor, and abundance of old boots. Get the next best thing with today’s Groupon to Audubon Aquarium of the Americas, located on Canal Street. The aquarium is teeming with sea life from a variety of far-flung habitats, featuring penguins, stingrays, sharks, and more. Walk through the underground tunnel of the Caribbean Reef and focus your sight-orbs on moray eels, angelfish, and other exotic creatures of the deep. Or float your raft along the Mississippi River gallery and encounter a white alligator. Young explorers will thrill to Adventure Island, an interactive area where visitors can touch cownose rays and even feed them at various points during the day with various feeding gestures.

• Really well done. Educational with the ease of entertainment. We couldn't believe three hours went by so quickly. The large tank of sharks and sea turtles with huge fish and sting rays were so much fun to watch. Felt like you were right in the middle of it. – Clevelandtravelerspm, TripAdvisor
• This attraction absolutely lives up to its name: you're cast into different environments from around the Western hemisphere. This is more than an aquarium -- it's a museum of habitats. – Scotty J., Yelp
