The beauty of an isolated piece of land is often contained in an area where few people ever go, so building an island resort is often a way to make profits by being exclusive. There are many companies that have done it, and the popularity of these complete entertainment and hotel areas continues to grow. It might seem like paradise to the guests, but building an island resort can be very difficult. There can be issues with getting the raw materials, housing the workers, and the expenses can be phenomenal.
It takes a lot of work to build any large edifice, and choosing a remote location ramps up the difficulty. For those planning a commercial venture of this nature, building it in stages is often the only way to succeed. Many of them begin with the central entertainment areas, and they have a few rooms or cabins completed by opening day.
