We have a condo this September in Lihue for 5 nights-my brother and his wife and me and my husband. We would like to see a good portion of the island and enjoy the beaches. Does it make sense to take a 1 day tour to get the overview of the island and then go back to particular spots of interest? Does anyone have a suggestion for a 4 day itinerary for driving and sightseeing? Thanks for your help!
