Over the years we have had several housekeeping issues. Many occurrences simply have to do with the complete lack of acknowledging requests:
Our trips are usually 8 nights or more and thus we get a full cleaning day. We also usually order another full cleaning day on the the towell and trash day (it is less costly for that day because they subtract the usual cost of the trash and towell service from the full cleaning day service). Over a period of twenty years, housekeeping has blown providing the extra full cleaning day when requested about 80% of the time. If you make the request through MS before you arrive, housekeeping never gets it, or at least claims it did not. If you make the request at the front desk when you arrive, same result. The only way it ever really happens is when you call housekeeping itself and order it when there, and even then the only way to assure it happens is to make a second call the actual morning of the service and remind housekeeping of the request. Once I called housekeeping and requested the service and was told it would be provided; when it wasn't I called again and got the same person I had talked to previously who tried to claim he had no record of my request. In addition, even for the full cleaning day that comes with booking 8 nights or more, housekeeping has failed to show up 20% of the time.
Another request never received or always ignored is time of cleaning. We often request through housekeeping when there that the cleaning on any full cleaning day not be done until the afternoon because we often are still in the room until late morning. Despite that request, housekeeping has still knocked on the door at about 8:30 wanting to clean the room and the person has no knowledge of the request we made. I am zero for all requests on that one because invariably I have gotten the knock on the door in the morning. I have even had the knock on the door twice when the do not disturb sign was on the doorknob.
I have had numerous poorly done full cleaning days. The worst was when we came back to our 2BR at 10 p.m. and found the full trash bags sitting near the door, the vacuum sitting out, the living room, kitchen and dishes not done, and only one bedroom and bathroom done. I can only assume the housekeeper took a lunch break mid-service and decided to never come back. Other issues have included one of the rooms not being done, dishes not done, trash not emptied, coffee pot not emptied and cleaned. We have some good cleanings but far too many bad ones.
If the new changes will improve DVC housekeeping I am all for them. As Maistre Gracey mentioned above, it is 20 years overdue.
