Next month the wife is dragging me to Hawaii.

I know it completely sucks but hey someone has to go.

We are staying on Ohau just outside of Wakiki. Neither one of us has been to Oahu before so we are kind of at a loss as to what we should go see and do.
So I'm seeking some guidance and advice on where to go and what to do. We will be there for 10 days. The wife will be in a conference for 5 days while I get to enjoy mysef the entire time we are there.

. Is there anything I should go and see that the wife shouldn't or wouldn't like? Is there any restraunts or anything that we HAVE to go see?
Thank you for any recommendations....I appericate it.
