Absolutely gorgeous location! The surroundings are stunning and the night sky is spectacular! You can stand out on the deck and see the ocean and the mountains- it's a perfect get-away!
It's a bit off the beaten path, so I would recommend being prepared to drive a bit to get there from the airport, and also if you're planning on doing any hikes or shopping.
I would also highly recommend picking up food on your way, or going down to the ferry port beforehand, to make sure you have food for meals while you're there, as the restaurants/grocery stores close quite early, and, as I mentioned, it's a bit of a drive to get around.
