Excellent resort with wonderful amenities. Briana was very detailed in her communication and made the check-in process very easy. Our room was comfortable and clean. All of the staff were wonderful and extremely helpful. The grounds are beautiful and well maintained. I do have to say that resort was crowded and all the pools were full of kids except for the serenity (quiet) pool. This is definitely a great place for families. For some quiet time, we were able to reserve a cabana a day ahead of time which made our experience a lot more relaxing. Overall, we loved staying at Marriott Ko Olina and can’t wait to go back!
