I just wanted to add that if you ever wanted to go Skydiving, Oahu is one of the cheapest places to do it in the world. (safe as well, don't worry).
I was there in August and went with
Skydive in Hawaii - Oahu Skydiving - Honolulu Skydiving - Pacific Skydiving Hawaii, they picked me up from my hotel, and dropped me off afterwards. Skydiving right by the beautiful blue water, it was amazing. Don't bother spending $100 on an extra diver to get a camera, for $40, they can get the guy to carry a gopro, and take pictures of you (they do a good job)
