My opinion is not every trip can be perfect. Pretty amazing any vacation spot gets the amount positive reviews that
dvc stays get.
I will not get into detail, as I did when we first came back form a trip that we experienced a bad room. Ours was a GV that had a mildew smell. Eventually, we got a different GV, same resort. But had to spend 1 night in a 2 bdrm. Points were adjusted appropriately. A hassle, yes. Ruin our trip or future trips, no. They also mailed us 6 FP's for a future trip as a gesture of good faith, which I thought was nice of them.
