I recently was in Kauai and stayed at the Waimea Plantation; a rustic resort that I said you must know what you are getting into. The Royal Kona, in the town of Kona on the Big Island, is another place that you will enjoy if you have realistic expectations. It is not fancy, it is not over the top, it is not modern. If you want somewhere that is uber deluxe, there are probably better options north of Kona. However, the Royal Kona Resort, and Kona in general, is a great casual place to relax and have fun.
I have stayed at the Royal Kona Resort three different times. The price cannot be beat. The first time I stayed was for my sister’s wedding and they treated everyone right. Now it feels like a second home.
