Twin River had sought to diversify itself geographically because its Rhode Island casino faced an increase in competition from casinos to be built in Massachusetts. In 2014, Twin River Worldwide Holdings (later Bally's Corporation) bought the property from Leucadia National for $250 million. Other concert performances in the first month of business included Kid Rock, Poison, Ratt, and Cheap Trick. ģ Doors Down opened the hotel on July 5, 2007.

Rebuilding of the facility was completed, and the casino opened to the public on June 30, 2007. Premier later began architectural work on a newly rebuilt facility, awaiting resolution of the dispute, prior to workers securing the property for the 2007 Atlantic hurricane season. Reconstruction and reopening of the property was in limbo for a time because of a legal dispute between owner Premier Entertainment and the trustee for bondholders on the property. However, days before the scheduled grand opening, Hurricane Katrina struck the Gulf Coast, destroying the casino and damaging the resort. The resort was constructed in 2005 and originally scheduled to open on September 1 of that year. It is owned by Gaming and Leisure Properties and operated by Bally's Corporation, under franchise from Hard Rock International.
