Leave the kids at home because this event is definitely for adults-only. Barenaked Ladies have signed on to perform at this year's big 5th anniversary celebration. Over 50 varieties of margaritas from participating brands will be available. This is a ticketed event with options to upgrade the fun with two additional margarita experiences, the Grand Marnier VIP Experience and the Grand Tequila Tasting. The party will end with an over-the-top fireworks display and plush rooms offered at special rates from boutique hotels like Epicurean and Aloft.
