Kauai for nice quiet "old school" vaca. Maui for a tick or two above that, the surfing is great here!! If you go to Kauai, dinner at The Beach House at sunset will take your breath away!! The Hyatt is unreal too, great golf, amazing location. Stay away from Oahu, just a dirty city in the middle of the Pacific, unless you want to do a day trip for the history of Pearl Harbor.
