My husband received an offer at my parents address recently and the only way they have his name and that address if from a trip he booked seperately to meet us down there about a year and a half ago. So this had to be from that. About 2 weeks later I received one at our house this time in my name, when I called to look into rates they didn't have my email address correct either so I changed that with them. I think they get it from a variety of sources...
