Before the discovery of the balloon, it was thought that the only essentials for a party were friendly guests and a CD of whale screams. Get ready for a modern get-together with today's Groupon: for $149, you get a two-hour party-bus rental from Sobe Party Bus (a $300 value). This Groupon is valid for services throughout Miami-Dade County.

The Sobe Party Bus's careful chauffeurs escort up to 18 passengers around town in a spacious party vessel loaded with luxurious amenities. During the two-hour rental period, riders tickle their optic nerves by gazing at the flat-screen TV's 22-inch display or watching as vivid LED and laser lights fill the interior and jump from person to person like radioactive fleas. Thirsty customers can use ice from the minibar to chill a beverage brought from home, then wash down a snack or toast to an adventure-filled night. The party bus also features a booming speaker system with a microphone, perfect for providing commentary as passengers waltz with the centrally located dance pole. Before embarking, partiers-to-be should carefully read the rules, which contain an encoded password for unlocking the bus's secret petting zoo.
