OneCaribbean.ORG is the Official tourism business website of the Caribbean Tourism Organization. On their site (www.onecaribbean.org) you will find statistics and market research, news and media information, events and calendars and a ton of other resources.
While it is no surprise that tourism is down in the region, it is a surprise to see some destinations increasing international visitors. See Guyana in June. Anyway the stats are by country and month and summarize the origins of visitors.
Check it out.
