I disagree with the idea that the Sheraton Waikiki is superior to the Moana. Stayed at both multiple times. Moana has a wider range of rooms, from poor to fabulous, but even the suites at the Sheraton Waikiki aren't that hot. Also, the Sheraton Waikiki is huge, with a convention center feel and very little sense of place.
BTW, the resort fee is the same $20.94 at all three properties.
