This island generally has it all - crowds, quiet areas, shopping, dining, surfers, golf courses, etc. It doesn't generally have the remote tourist feel. If you don't want see people and pavement, you probably want to choose another island.

My wife and I spent 5 days on Waikiki as part of our honeymoon. Since it was beautiful and we are much more activity people than beach bums, it really put us in our element. We traveled to Diamond Head, cruised through the North Shore, went to the Dole Pineapple Plantation (good honeymoon experience - get lost in the maze at the plantation - its a good indication of how you work together), saw the zoo, and generally had a blast. If you haven't been here before, there is a tour bus that goes to anything - you just have to ask.
