If you’re afraid it will rain on your vacation week, you might want to buy protection.

Ahhh, a full week at the beach. But what if it rains? 

There is insurance for that. According to Jeff Boyd, CEO of Priceline.com, several online companies are offering what they call "vacation insurance," deals in which they will reimburse any parts of a vacation that are ruined. He also says Priceline’s weather insurance will cover you if your vacation is rained out. 

Travel or weather insurance generally costs about 4 to 8% of the cost of the vacation, but be careful before you purchase it. In most cases, it will not cover last minute trips where bad weather has been forecasted. You’ll need to buy the insurance well in advance of your trip.
