According to news reports, Mohegan Sun has added a water park and a second hotel to its proposal to build a gambling resort in Palmer, Mass. The company is in competition to win one of three casino gaming licenses to be awarded by the Massachusetts Gaming Commission. The changes to the Mohegan Sun project bring the projected cost to almost $1 billion. The commission has said it will award two of the resort commission licenses -- for regions A and B, the eastern and western parts of the state -- by February 2014. There is no timeline for when the casino license covering the southeastern part of the state will be announced, as there is a possibility that a tribal gaming property will be built there. According to a gaming commission spokesperson, the Mashpee Wampanoag tribe is working on a deal with the state; if that materializes, no third casino resort license will be awarded.
