We just got married (October 2007) and we went to Hawaii (Oahu)
It was a lot of fun - somewhere we hadn't been before, that was completely beautiful with a lot of different things to do. We stayed on the opposite side of the island from Honolulu in a little rental house, so it wasn't crowded and crazy, but still easy to get everywhere with our rental car. Plusses about Hawaii: we didn't have to fool with passports and customs (and yet it might as well have been a different country from here!), and it was a compromise pricewise (not as expensive as a trip to New Zealand, not as cheap as just going somewhere in GA).
Anyway, loved it!
