Mohegan Sun, the new operator of Atlantic City's Resorts Casino Hotel, said some of the refurbishment work on the gambling facility has been completed. Construction on the $35.5 million Margaritaville project at the casino resort has also begun. "I firmly believe this property is going to turn a lot of heads in Atlantic City this summer, with all of the new amenities and a redone casino floor. It's going to be quite beautiful," said Mohegan Sun CEO Mitchell Etess.
