The Discovery Inn has the prettiest yard/garden of any facility of its type that I've ever seen. I would have loved to have had breakfast outside but unfortunately it was very damp. Even if the Inn was not as comfortable as it is, it would be worth it to stay here just for the setting.
The Discovery is an older building that has been tastefully and attractively updated. It has a new bathroom and a very roomy main room. There's a microwave and frig, and other thoughtful extras that make it comfortable. I slept extremely well there.
My only suggestion would be a large mirror in the main room so one person could be doing makeup/hair while the other was using the bathroom.
If you are wondering why it is called an "inn," I'm not sure, it seems like a nice motel to me, which is not to disparage it in any way.
Keep in mind when judging the value of anything on island, that everything has to be shipped to the islands so things do cost a bit more. The business owners aren't trying to take advantage of tourists.
