In this December 15, 2012 file photo, revellers dressed up in Santa gather at Trafalgar Square in London during a SantaCon festival in London. SantaCon events unfold in more than 300 cities worldwide and the New York celebration is one of the biggest, but complaints about boorish, bar-hopping St. Nicks at previous SantaCons got attention from local officials and the NYPD.
