I went 3 times in the last year - rented points the first time, stayed on-site under my name the other two. I received the pin for the feb-march offer (was it 20%? 30%? something like that) in january, the day before my most recent trip.
My mother has travelled with me each time, and also went two other times in recent years with my brother's family. She has never had a reservation in her name,, though. She received two pins - one came last fall, i don't remember the details. Then she got the 40% off one, so we are using that together. We have received non-pin mailings in her name at my address (dvc, etc.). The pin offers went to her address though.
