5. My suggestion: in this economy, rent a car, stay at the Kauai Sands, and do all your beaching at Poipu or Kalapaki Beach, head up to the North Shore and visit Princeville, Hanalei Bay and the Hanalei Valley, and use the Sands and the area around Kapaa as your evening destination for dinner, walking around the Coconut Marketplace and sleeping there are an array of very good restaurants at all the hotels around the marketplace.
