I havent actually been there but there are some great webpages full of information which will help you know what to expect. I would suggest you have a look at the [url=http://www.destination360.com/north-america/us/hawaii/oahu/waikiki-beach]Waikiki/url] article, which offers your a virtual tour.
Things to do in Oahu and the
Waikiki Beach Hotels articles would also be very useful to you. With these pages you could eve find places of interest which you may choose to visit whilst on yout honeymoon.
I hope this helps :)
