Taking sister with COPD on her first (and probably only) trip to Hawaii. I want to take her to Kauai and love the north shore, but am concerned with her getting around. In Mexico we were able to find a place right on the beach and rented a golf cart which worked perfectly. Know we will just have to rent a car, but I am looking for any suggestions from people who know the island for a place to rent that she can maybe walk to beach. Maybe another part of the island is best?
