My sister posted yesterday asking advice on the best shore to stay with our 80 year old parents for 2-3 weeks to Kauai last week in Jan-first week in Feb. It was unanimous with Poipu as the choice. We'll rent a vehicle for day trips but would like to be located close to or on beach, easy walking for shopping and restaurants. Do we need a car to go everywhere or is there an ideal location in the South? And not sure whether to stay at a resort or private home. Ideally $300 - $500 a night for 5 adults. Any recommendations?
