Antsy employees, worried they'll have to bag their pricey getaways in the event of a downsizing, are shelling out for layoff insurance (a feature of many travel-insurance policies), which reimburses nonrefundable expenses, like airfare and hotel deposits. "People are feeling vulnerable," says Chris Harvey, chief executive of travel-insurance site SquareMouth.com, where sales of policies have doubled over the last year. Even blue-chip outfits like Norwegian Cruise Lines now offer their own layoff-insurance programs.

Before buying a policy (which can run as high as 8 percent of the cost of your trip), check the fine print. Some require that you've been with your firm at least a few years; others mandate you be a full-timer. Many provide coverage if, say, your tour operator winds up filing for bankruptcy—and there's not a Piña Colada on earth that offers that kind of peace of mind.
