Most of the time, vacationing in such a privileged location among the more than 400 islands in Belize is a pampered — and expensive — experience. A new Four Seasons resort coming to the island of Caye Chapel next year will offer over-water bungalows and access to a 10-hole golf course. Its rates are not yet published, but other private island resorts in Belize are known to charge more than $2,000 a night.
