Most of our trips to WDW were in deluxe hotels prior to joining DVC. I must admit that I was a bit surprised by the condition of the 2br we stayed in at BCV during our first trip as DVC members. As crisi said, they are a bit more worn than your deluxe rooms at the other hotels. The carpets and furniture had stains and obvious signs of wear in the cushions. The walls were pretty banged up.
HOWEVER, THAT BEING SAID, I would have a VERY difficult time going back to staying in a regular deluxe hotel room at WDW. Although some of the DVC rooms show more wear, they are MUCH roomier and come with kitchens and washer/dryers and in general are just larger accomodations. I'm spoiled now. I can't justify staying in a smaller room that doesn't even have a toaster or microwave when my DVC will. As far as mousekeeping goes, I'm one of those folks that PREFERS not to have to mess with them coming into the room and worrying with it. They interupted my kids' naps on trash and towel day b/c I forgot about them coming and didn't put the sign out. But their abscence is probably part of the reason for the wear on the rooms.
So for me, the amenities and size of the DVC rooms far outweighs that of any deluxe hotel room.
