Free Cruise/Disney/Vegas Vacation..attempt to sell timeshares? - timeshare cruise offer

I received one of these brochures in the mail saying I won a trip on the cruise ship, or other destinations such as Disney and Vegas. On the back reads: "adv used. Mat'l in order to solicit sales Vacation Ownership Plans." M, suppose you a timeshare.
Has anyone followed by one of these offers?
Id like to leave "free", even though I partcipate timeshare seminar. I had trouble believing that you give and give eventhough you say no to the timeshare.
