What is your favorite travel guide to O'ahu? I have never been to Hawaii and would like plan a trip so I need something for a knowledge base of zero. I would like to visit Pearl Harbor, Diamond Head, snorkle at Hanauma Bay Nature Preserve and take in a Luau. Also, tips for getting around and transportation options. I really like the "Unofficial Guide" books but the Hawaii one did not get such good reviews. I am looking for one that has an edition date of 2010 and up. Thank you in advance for all your help!!
