There are small and very rustic hotels on some of the islands, and due to the lack of restaurants, they offer all-inclusive meal packages. Also most hotels will include day trips to some of the smaller islands, where they will leave you alone for several hours to snorkel, sunbathe or swim. These Islands offer pristine white sand and crystal clear water, and coconut trees that offer natural shade from the hot sun.
Be aware that all the accommodations are very basic, often simple huts made of sticks as rooms - which is also what the locals live in. You hear your neighbours, you might see them as the walls are a little see-through at night if the lights are on inside, and you share a bathrooms with toilet and shower look alike.
