Everyone loves surprises, and Aloft Hotels used Microsoft Tag to create a fun contest for its guests. Aloft created three different Tags that were hidden in guest rooms and common areas. When a guest found and scanned a Tag, they were entered to win tickets to the hotel’s “Live in the Vineyard” event, a luxurious weekend in Napa Valley mingling with pop stars and artists. The hotel also promoted the contest on its Facebook page.
