We enjoyed our stay in the Hibiscus room and liked the "feel" of the Waimea Inn so much that we were fantasizing about returning and renting out the whole place for a family getaway. The staff were exceptionally helpful and kind. There is not much to do in Waimea; however, this inn is conveniently located near the road into Waimea Canyon and within 40 minutes of the Polehale State Beach. We loved the spaciousness of our suite and the old, plantation-type house had character. There was also a lovely, cool cross-breeze through our room, enhanced with ceiling fans. The beach/south facing rooms (Banana and Bamboo) would probably be warm in the summer, but each room has A/C.
For healthy eaters, food options in Waimea are quite limited. We never seemed to be able to catch Island Taco when they were open (they are only open between 11-5), so we bought groceries at the Big Save across the street. The Waimea Inn has a microwave and paper plates you can use. They also provide coffee and tea, with coffee maker and a mini fridge in the room. South Kauai is worth spending a few days to explore and the Waimea Inn is well-situated for excursions around the south and interior of the island.
