New Jersey’s casino enforcement agency recommended only a one-year license renewal for Tropicana Casino and Resort, citing mass layoffs and a litany of customer complaints under the troubled ownership of Columbia Sussex Corp. The recommendation by the Division of Gaming Enforcement will be considered by the New Jersey Casino Control Commission when it meets December 12 to make a final ruling on Tropicana’s license and the suitability of Columbia Sussex and CEO William J. Yung III as owners.
