This unit is in the Marriott located on the beach in Ko Olina. This is a top-notch destination resort with basically a public beach/lagoon plus multiple pools and hot tubs. While the beach is public, like all in Hawaii, most of the people are from the hotel and it takes the public an effort to get to this area. Thus, there is always space to sit on the sand or swim or generally enjoy yourself.
Photos suggest that the room's view is of the ocean, but it's of the mountains. (In fairness, there is a note that says the view can vary.) BUT, the ocean and pools are noisy so looking toward the mountains means this unit is very quiet, which we enjoyed.
Activities at this resort are plentiful. Snorkeling is good. Beaches are pleasant sand, and there is a sidewalk for walks or runs that goes some distance. Local market and shops are within a short walk. City stores are a 10 minutes drive: Target, groceries, and restaurants. We'd stay here again happily.
