NEVER REDEEM A VOUCHER FROM SPIRIT INCENTIVES! You can't pick the date you want to go on and if ANYTHING happens and you can't go, you WILL NOT get your money back! Unless you have no children, no job, no reletives, and no life at all, things happens and things change. You can only travel during Fall and Winter months as long as the date doesn't fall within 10 days of a holiday. Then, they will sell you something called "Travel Assist" which is supposed to allow you to change the date of your vacation one time in case somethin happens. But, when something does happen, you have to pay another $200 - $400 to change the date of your trip! The trip is not "free" as they would have you believe. I gave them nearly $600 to take a "free" cruise. This amount included the cost for govt taxes and fees, an upgrade to a regular interior cabin (the cabin they give you for "free" comes with bunk beds), and the cost of the travel assist program. Now, we can't go on the trip unless we pay extra money. Our money is gone and we can't get it back. Please don't make the mistake that we did. Book your own trip because nothing in life is free. And if someone tells you it is, they are lying.
