Sorry that your experience has been that bad on occasion. We have yet to see a dirty room or meet a rude CM. Every one of them has always gone out of their way to help us, even knowing that we are DVC. The rooms have always been clean and in good shape.
The one time we had an issue was with the SSR Treehouses. The living room TV had a scratch on the screen, and the shower door handle was loose. We called them to let them know about the handle and the TV (so they wouldn't think that we had damaged it), and that it wasn't a big deal to wait until we left a week later to replace it. The maintenance guy was over in less than 30 minutes to fix the door handle, and a manager showed up 5 minutes later with a brand new TV in the box. Even though we told them that it could wait, they insisted on swapping it right then and there. They asked if everything else was good before they left. That is the type of service we have always received as DVC members.
I completely agree that they seem to have left a BCV refurb a lot longer than they should have. At least the new regime is recognizing that the old schedule was too far apart, and have now adjusted the refurb schedule for all resorts. This should help in the long run.
If you don't mind relating it, exactly what experience did you have that they were unwilling to do anything for you because of the fact that you are DVC members? If it's too personal, I completely understand.
