First off, I want to say this has to be the best way to see the island! No worries about getting back to a hotel, or getting one of the few rental cars on the island right now! There are plenty of beautiful places to camp, both right on the beach or in the forest, whichever you prefer! I would highly recommend this.
However, there were a few things that did cut into our enjoyment a bit. For example, the battery alarm went off every night even when the fridge was the only thing running and woke us up after 4-5 hours. I know the owner is busy, so hopefully this isn't an issue in the future.
That being said, we loved being able to wake up at the beach every morning and the freedom to travel around the island! Wouldn't have done it any other way!
