Things to do:
Sunset Cruise, we boarded the boat thingie kinda in front of dukes on the beach, it was absolutely wonderful, they give free drinks while your out. Go to Trip Adviser and search on the hawaii sites for honolulu area, i did alot of research and had a great trip, the entertainment book had coupons $off at pearl harbor, and discounts for several luaus' the book oahu revealed is a great help, can get at the book stores or amazon, etc. We climbed diamond head early, but it was July 05. Drove around to the north shore, thats worth the trip in itself, a couple of hours up the coast. Pearl Harbor, arrive early 10ish. There is so much to see and do, dont let them scare you about driving in Honolulu, once you figured out the streets it was no problem. I know there is alot more. I had a wonderful trip and cant wait to go back again.
