Does the marriott have shuttle service like the westin?

Marriott's Maui Ocean Club is a regular stop for the free Kaanapali Trolley. The Marriott is the southernmost stop (also services the Hyatt). The full circuit has several stops, including Whaler's Village, Black Rock (Sheraton), the Kaanapali Golf Courses Club House (two 18-hole courses with ocean and mountain views, plus Roy's restaurant), the Fairway Shops, and north of Black Rock to Maui Kaanapali Villas. No cost to ride, but please remember to tip the driver.
