WASHINGTON (AP) - Being a big fan of "Duck Dynasty" has given Scotty McCreery the chance to sing at Sadie Robertson's Sweet 16 party and now, he's going to go on a cruise with the family. The Duck Dynasty four-night cruise to the Caribbean sets sail a year from today. It's a chance for fans to meet and party with the Robertsons. McCreery will provide the entertainment. McCreery says he has "a feeling this one will be a little different from most cruises."
