Say, I bet the travel agents phones are ringing off the hook. Good deals to be had, no doubt!
just for example. i really don´t know how this is managed in the US but in my country if the state declares a official traveling warning. you are allowed to get back all your money which you may have invested in your personal trip. So once my state declares a official travelling warning i can change my flight, hotel... and the companys involved is forced to return every single cent i may have invested in this trip before. So usually the state is extreme carefull to declare a official travel warning because it will cost the economy millions of dollars.
