We enjoyed our stay! Ken was very accommodating. We enjoyed the garden room and breakfast. It’s very close to the airport also! He has a hot tub you can dip in and watch the sunset. It was gorgeous out there.

Top notch staff, superb food, Great bartenders, bathroom and room extremely clean. Only thing to advise other travelers about is prices in restaurants. Food is outstanding but is not cheap, you get what you pay.for.

The restaurant serves the BEST burgers we've ever had. I wasn't pleased about the parking fee, and the rooms are a little aged.
