Timeshares throughout the world have done wonders for tourism especially in the "off" seasons,and IMO they should work well here-it is just that one has to make sure that the resort is fully owned by the directors/partners with little or no borrowings-the problems that I have seen with the industry is that many resorts open and close due to large scale debts and invariably the people who have bought a timeshare are the secondary lienholders and get,in the end, nothing for their investment,as the bank or loan company is the first,and grab every asset-this is a general statement of timeshares worldwide and is not aimed at Costa maya as I have been informed by the new owners that they own the resort outright.
