The Marriott Ko Olina and our unit were both absolutely fantastic. Check in and out was easy and smooth and the front desk was always super helpful. The resort itself is beautiful, relaxing, and fantastic for kids. We had four adults and two little kids and felt like the two-bedroom unit was plenty of room. Colm was responsive and kind. We can't wait to come back and are already looking at booking another trip in a couple months. We've been to Hawaii every year for 6 years and this was our best yet!
