Travel America Vacations, Inc Beware of Free Vacation Ferndale Washington

I leased a car 1 year ago and with the purchase they gave me a certificate for a Free 4 Day Cruise with Carnival for 2 people,  that expires in June 2015. I called on August 6, 2014 to get details on booking a cruise, the customer service told me that this entitles me to a cabin with a twin bunk bed and they only had dates available in January 2015 and the Booking/Port fees are $198.00 per person, so I asked what if I wanted to upgrade to a regular double bed cabin and she said it would then be $297.00 per person. and if I wanted any other month it would then be $400 per person. I can book a cruise on my own for about the same as this so called Free Voucher. Travel America is a Rip Off.
