We had a great time over the Christmas and New Year's holidays at the Marriott Ko Olina. The host was quite responsive in helping set up the reservation. The experience is much like any other resort, except you are going on an owner reservation under your name. Ko Olina is a 20-year-old, master-developed community on the west side of the island that consists of the Marriott, Disney Resort, Four Seasons, Beach Villas, and private houses. It is a great place to spend time with your family without the hassle of having to deal with Honolulu/Waikiki. During high season it can get quite busy. Still, the multiple pools, restaurants, family activities, and the clean private beach on one of the artificial lagoons make it a fantastic setting for a family vacation.
