I have been to Maui several times, but this is our first time to Kauai. We tend to make several reservations ahead of time to special places, but then decide the rest as we go along depending what we feel like. I am seeing many posts that people have their entire vacation planned with reservations for all days before they arrive. Is this necessary in Kauai? We have reservations for Kauai Grill, Beach House and Plantation Gardens. Any others necessary?
