Ah Hawaii....man, that brings back memories! I use to go every winter with the family I nannied for, rough job I know!
Anyway, as you plan your lovely second honeymoon, and planning and dreaming are half the fun, right

, a few words of advice. Don't try and do a bunch of islands, pick one or two and savor them. Personally, I would skip Oahu entirely, too much like a lot of big cities, albeit with Diamond Head for a back drop but still...I would spend time on Maui for fun and Kauai for relaxation. There is tons to do on Maui, siteseeing, swimming, snorkeling, sailing, the Sugar Cane Train, Whale watching (in the winter/spring) Haleakala, man, I am making myself "homesick"

Kauai is much more laid back, lots fewer people, plenty of time to sit on the beach. I have tons of pictures but no scanner, bummer. Let me tell, you though, they are some good pictures!
Have fun dreaming!
