We had a wonderful time in Kekaha. Amy's house is beautiful and there is an ocean view from almost every room. The location is fairly far from the main attractions (Lihue, Hanalei) but we planned it that way. We made reservations for several activities and just planned the driving time and had no issues at all. Polihale State Park is a must! We spent a day there and practically had the whole beach to ourselves.
The only recommendation I would make is to research restaurants and make reservations before you arrive on the island. We were only able to get reservations for one evening. That said, we found several local places that had great food and service.
Lovely place and one I would love to stay at again on our next visit.
