I stayed with a friend that lived in Waikiki so I borrowed his bike and went all around. I definitely know what you mean by the poor parts of town. I can't say I agree with you on the beach part though because I saw so much sand and thought the beaches were very nice (especially in the touristy areas). Perhaps the Carribean beaches are nicer though; I wouldn't know cause I've never gone. I had a pretty good tour of several trails, Hanauma Bay, and sight seeing on the island.
