PARADISE ISLAND, Bahamas — Many of the biggest players in the Caribbean tourism industry have gathered here for the annual Caribbean Hotel and Tourism Association’s Caribbean Travel Marketplace conference. It is the second year in a row that the Bahamas has been the host country for the conference; it has been held at the Atlantis resort each time. The conference joins suppliers, such as hotels, restaurants and tourist boards, with buyers — tour operators and wholesalers, along with heavy industry-focused discussions.
