Never been upgraded actually, but we were offered another resort once we went to check in because they overbooked the preferreds. Of course, we were fine where we were and we ended up with a great room the next day they moved us into a fabulous preferred room. However, when we called for our ressies for this year, when my dh was on the phone she asked if we'd stayed at WDW before he said yes they pulled up the name and she says oh you've been here 12 times in the last 6 years alone....she was laughing and said something about living near there and he told her no we drive from Michigan a few times a year or at least once. He says if you look up my inlaws last name you'll see how many times we've really been there....just for fun she looked it up and said holy cow, you might as well move in here. The point being.......they know how many times you've been there how many kids you have when you usually come etc....I think when they see very loyal people and they can do it, they will upgrade you as a show of appreciation maybe. But with ME at the healm it happens less and less.
