Before scientists discovered that the Earth rotated, people thought the sunset was a result of the sun god's descending chariot or the avant-garde experiments of the impressionism god. Reorganize your worldview with today's Groupon: for $91, you get a sunset dinner cruise for two, with VIP reserved seating (up to a $182 total value) from Ali'i Kai Catamaran Cruises. Roundtrip transportation from Waikiki is included in today's deal.

Aboard a 170'x50' catamaran, dinner cruisers with Ali'i Kai taste piquant Polynesian dishes while watching traditional tribal dance in front of a stunning ocean sunset. During the two-hour dinner cruise (up to a $79/person value), complete with a lei and an additional alcoholic beverage (a $12 value), palates can experience new island flavors with buffet items such as the spicy pipikaula salad, pulehu cilantro-lime-marinated beef, or the mango-pineapple-teriyaki-glazed chicken. Vegetarians who call or skywrite their preferences in ahead of time can nibble on a specially made meat-free meal.

As stomachs transform scrumptiousness into nutrition, a local dance troupe churns its hips in rhythm with hand drums, shaking straw skirts and seashell necklaces to indigenous syncopations. These body undulators will then clear the stage for the subsequent dance party, in which guests are invited to strut their stuff and join in staff-led social games such as a conga line and full-contact Trivial Pursuit. Fortunate journeyers may encounter surfacing whales, dolphins, and turtles native to the Pacific.
