Pitch it Cruise Dad. Carnival does not open "new locations" in anyone's area.
It's a pitch to join a "travel agent club" where they claim to let you into their travel agency so you can get better prices on travel. They charge a huge fee to enter the club and the savings never materialize. The free cruise isn't. You end up paying more in fees and taxes than you would have if you just booked a cruise yourself. I have seen several discussions of this very same scam postcard.
