You then select your travel dates (including specific flights), choose some optional extras like ground transfers and activities, and book the trip. A week before you leave, CheapCaribbean reveals the exact resort you'll be calling home for the next few days, and you get a trip at 50% -- or more -- off the price you'd otherwise pay.
But these deals are only good during off-season, right?
You pick your own travel dates, and can sometimes book up to six months in advance, so you can get these deals any time. You can literally book the day before if you want, it just depends HOW impulsive you want to be. Of course, just like with full-priced travel, you'll find better deals and lower prices during slower seasons. But that doesn't mean you won't still find 50-75% off discounts during, say, spring break or Christmas.
