We just bought
DVC this year and based our purchase on approximately 10 nights per trip including weekends. For our first trip we are staying Tuesday to Friday for 10 nights and don't want to deal with the hassle of moving out and back in to save points.
We live far enough away that we won't be making more than 1 trip per year, so I just want to settle in and enjoy myself. When I think of a relaxing vacation, I don't think of changing hotels twice during a trip. A Disney vacation is hectic enough. I want to unpack on day 1 and not worry about packing again until it is time to leave the World.
That said, if our trip ended on Sunday, I would consider moving to another Disney resort on Friday, since we would not have to move a second time. Plus, I'm gonna miss staying at Coronado Springs, Dixie Landings and the Polynesian.

I will never stay off-site again.
Maybe when our sons are older, the idea of moving around will seem more appealing, but for now I'll just settle into my home away from home.
