It can be a challenge to build any large complex, but creating a resort venue on an island is a complex matter when it comes to the logistics. Unless the island is large enough, each piece of equipment and building material must be shipped in. Most items come by boat, but a few could be flown in if the island is large enough to have a landing strip. It raises the cost of construction, but it can also hamper the building schedule if stormy weather creates shipping delays.
For those developers lucky enough to have good weather and reasonable shipping costs, labour can become an issue. Many modern resorts are built on islands with little or no indigenous population, so workers must be recruited and housed. Finding people willing to be isolated is often costly, and setting up even temporary housing facilities will have to be done before any of the resort can be built.
