Polynesian Adventure Tours/Gray Line Hawaii was founded by Bob George and Don Brown in 1977 on Oahu. It has grown into the acknowledged premier tour and transportation company in Hawaii. The Maui office opened in 1985 followed quickly by the Big Island and Kauai. Polynesian Adventure Tours/Gray Line Hawaii currently employs more than four hundred staff members. Building on its success, Polynesian Adventure Tours/Gray Line Hawaii has developed a robust business not only servicing tours but in providing for the needs of private charters and group movements. After being acquired by NCL America in 2004, Polynesian Adventure Tours expanded its shore excursions enterprise, not just for NCL but for most of the major cruise ship lines who port in Hawaii.
