We are thinking about returning to Hawaii and haven't decided on an island (or two) to visit yet. Pretty sure it won't be Oahu since we already spent a week there and only less than 2 days on each of the others (part of the Pride of America cruise). I felt like a second class citizen at the Marriott Ko'Olina when I booked with points, so I'll probably avoid vacation club locations unless there is a strong reason to stay somewhere where the only view I can get is of a parking garage.
We really enjoyed the Courtyard in Laie and received a beautiful upgrade, but it didn't have the wow factor of the Ko'Olina or the non-Marriott property that we stayed at right on the beach in Waikiki.
I think this is my location preferences in order, but I keep changing my mind here:
Maui (anywhere on the island)
Big Island Kona side
