Looking at lights and drinking wine has become one of man's top holiday activities, just after studying gingerbread house architecture and contemplating infinity. Let seasonal twinkles and a cup of good cheer entertain you with today's Groupon: for $55, you get a holiday lights wine tour, which includes a wine tasting, bus ride, and live caroling with 5280 Wine Tour CO (a $130 value). Each holiday lights tour starts with a tasting at D'Vine Wine located downtown, where revelers will get to sample three vine varietals. They'll then board the warm luxury bus to enjoy a cheery trek through the city’s brightly bedecked streets, complete with seasonal festive sangria, cookies, and live caroling. The wheeled wassailing tours run twice nightly, Wednesday–Sunday at 5:30 p.m. and 8:00 p.m., from December 1 through December 30 (some blackout dates apply).
