I got that mailing this week too. I agree it was tacky. The letter said something like "since you recently sailed on the PG, we would like to know what kind of French Polynesia itinerary would appeal to you in the future" and sounded like a survey. Then on the response card it said something like "Please send me information on the following itinerary" with a few choices. Easy to see that it wasn't really a survey but a brochure/information request. It also struck me that if their database was really effective, they would already know that we are booked on the PG for December 06.
