Aloha everyone! While I have been to Oahu, I haven't ever been on that short of a trip. I have some friends who have a 7+ hr layover in Honolulu as they travel back from Fiji before heading home to Alaska and they have never been to Hawaii.
I think public transport would take too long - would you rent a car or just get a taxi?
Would you be able to squeeze in Pearl Harbor? Or would you just go to Waikiki and hang out? I told my friend I would come up with some ideas for him by the end of the day. They would love some good local food - and I think they mean by that fresh fish, etc. Mahalo for any suggestions that would make this workable and fun. :)
