We're trying to do a better job taking in the sites around Oahu. Last weekend we went to the Pacific Aviation Museum and this weekend we went to Shangr-La, Doris Duke's home and now Islamic Art Museum.
We have done a lot of site seeing and tours in our journeys and we are now 100% convinced if there is a guided tour, pay the extra and do that. We've have never once had a bad experience. The Pacific Aviation Museum has such a docent lead tour and it was great. I think it was \$10 extra, but worth ever penny. We also got a Kama'aina discount by showing our Rainbow ID Card (HI Driver's license). We didn't quite work the deal right though as we could have got one ticket for Kama'aina AND buy one get one free. Gotta figure that one out when we go back for the other exhibits at Pearl Harbor.
Shangri La was once Doris Duke's private residence, but it was also designed to be what it is now a Museum to Islamic Art. The building and the grounds are absolutely beautiful. You're not allowed to take photos inside, but this panorama of the view to the ocean gives you a taste. This is a must see if you make it to Honolulu.
