(Undated) -- It took just ten weeks for Disney to find a million volunteers who were willing to give a day of service in exchange for a day's admission to its U.S. theme parks. The entertainment giant announced late yesterday that it is ending its "Give a Day, Get a Disney Day" promotion, saying that all of the tickets dedicated to the program have already been allocated. In 2009, Disney gave away tickets to guests who visited on their birthdays.
