One of  top five off-peak destinations for Fall 2012
Curacao, one of the Caribbean's ABC islands, is a top-notch fall destination for shrewd budget travelers. Like other Caribbean hot spots, Curacao sees fewer visitors in late summer and fall than in, say, the busy winter or spring-break seasons.
From mesmerizingly decorative buildings to lush coral reefs beneath sparkling turquoise waters, the Dutch Caribbean island of Curacao has more than enough sights on land and under the sea to keep visitors restfully busy for a week.
If you're reluctant to jet to the Caribbean during hurricane season -- from June through November -- Curacao's a good bet.
