Planning a 2 week trip for 2 (big bd and anniv) in late Sept. Have been to Oahu and Maui. Would like to go to Kauai and the big island and possibly back to Maui, but that seems a bit much. I have been to the big island before, but it was over 30 years ago, so that does not count. My husband has not been to the big island before and neither of us has ever been to Kauai. We have some Marriott miles saved up-probably enough for a week. Any advice on how to plan this vacation/where to go/what to do/where to stay? Thanks!
