I guarantee you this is just promotional junk mail to try and sell you timeshares. You go listen to their hard-sell sales pitch and at the end you get the tickets... except the tickets are loaded with restrictions, expire at a certain date, and are airfare only (no hotel or anything else).
EXACTLY RIGHT! I JUST CALLED AND THE LADY WHO ANSWERED WAS READING FROM THE SAME OLE "TIMESHARE/VACATION RESORT" SALESPITCH SCRIPT. I SHUT HER DOWN AND HUNG UP.
