This summer, plan on writing your own ticket to the Caribbean. Maybe not everywhere, but to lots of places. Places that are actually nice. Example – $159/night at the Westin Casuarina Resort on Grand Cayman’s Seven Mile Beach. From June 1-September 6. That’s not oceanview; Oceanview is $209. Still.
