Enjoy this review of the Marriott Ko Olina Resort on the west side of Oahu, a good alternate choice to Waikiki for families who want a change from the hustle and bustle of Honolulu. Ko Olina is set in a series of lagoons, next to the Disney Aulani and Four Seasons Resorts. This is a time share property perfect for renting directly from the resort or exchanging your timeshare week elsewhere for a week in paradise.
