Introduction Finally, the Mauna Kea Beach Hotel is under renovation but is scheduled to open next spring. Located on a beautiful, wide beach, this was originally a Rockresort. I couldn't see any of the renovated guestrooms. I did see a photograph, but it's hard to judge the quality of the furnishings from a photograph. We did see some rooms at the adjoining sister property, the Hapuna Beach Prince Hotel, which claims to be 4*. The rooms smelled musty and not up to the standards of your typical ... Marriott.
