Celebrity Solstice, Golfing on the Green

Celebrity Cruises announces The Lawn Club, a half acre lawn for putting and bocce ball on its new ship, the Solstice. Can't wait to see how this "plays out." Fore! Conked heads? Or, more to the point, which grass did they choose (apparently after extensive testing) to withstand huge foot traffic, sun, salt air, and the humidity of the Caribbean?
