The 112-unit, oceanfront property shares amenities with the adjacent Waikoloa Beach Marriott Resort & Spa.

“We’re thrilled to add another world-class Marriott Vacation Club property to Interval’s growing network of quality resorts,” said Marcos Agostini, executive vice president of global sales and business development for Interval. “In addition to an idyllic setting, our members can enjoy luxury accommodations and an extensive array of services and amenities.”

“With the addition of Marriott’s Waikoloa Ocean Club, our first on the Big Island, we now have a total of six resorts throughout Hawaii and are excited to offer more options to our Owners and guests. The mix of natural and cultural wonders is absolutely spectacular,” said Ed Kinney, global vice president of corporate affairs and communications for Marriott Vacations Worldwide.

Overlooking the tranquil waters of Waikoloa Beach, the pristine resort offers multiple lagoon swimming pools (including one for children); waterslide; onsite beach; fitness center; tennis facilities; and cultural activities, such as lei-making classes and hula and ukulele lessons.
