We have never used housekeeping other than the standard ones you receive. It is nice not to have people in the room when you are gone. You can leave things out if you want etc. Not sure what the costs are, but someone will know. I know it is linked to the size unit you are staying in. We always make our bed at home when we get out of it, so that is just as easy to do at WDW too. We throw our towels in the washer when we go out the door and in the dryer when we return for our midday break.
