Fortunately I own at the coolest DVC resort ever (VWL) so if I could only ever stay there I would not lose sleep, especially if I could buy resale points for $25 each because DVD restricted them and killed their resale value. It's all in your point of view, I don't think they'd do it but who knows. I am firmly in the Buy Where You Want to Stay camp so you can avoid these problems, while its nice to switch up resorts the people who will be really upset are those who bought one place ( to buy direct or cheap resale) but intended to always stay somewhere else. BTW, VWL is my coolest resort which I know is arguable . But you should feel that your home resort(s) is the coolest ever or don't buy there.
Have fun.
