But don't the greatest majority of timeshares have either a Friday to Friday or Saturday to Saturday schedule? So they can hire a whole bunch of housekeepers just for Saturday or just for Friday? DVC has to have the same number of housekeepers everyday of the week.
I'm not sure most is accurate but certainly many would fit into that category. Those that do often have people arrive early and late, do developer previews, and many participate in some type of points system so it's not as concentrated as you think. They have some staff every day and a few extra on specific days. I suspect most have dedicated staff and rotate days off and arrival times rather than having just part time people for busier days though I'm sure some do that as well. Plus I'm sure DVC has days that are inherently busier than others in this regard as well. IMO, the setup at DVC should make them better at planning and more efficient, not less so. IF they could get the job done consistently with housekeeping, it wouldn't be an issue. There are many ways to approach this. You can have several staff gang up on a given room to get it done more quickly, you can establish a good and workable system for determining which rooms are vacated early, get some staff on site and working for those units that were vacated very early or even the night before. From what I've seen, the DVC resorts, esp the stand alone DVC resorts, don't do this job as well as many of the off site resorts do. I'm not saying they're bad, just they could and should do better.
To expand a bit and digress, lets look at Marriott at Orlando and HH for example. For Orlando they have now 7 properties. Of those, 3 have 5 check in days, 1 has 4 check in days and the others have 3 different days. For HH, it's a little different. Of the 8 properties, 3 have Fri, Sat and Sunday. Of the other 5 all have only one check in day but 3 are Sat, one Fri and one Sun. I'm assuming they share staff to a degree. And even for single resorts, the staff often works at more than one location including hotels and other timeshares. Thus there are other ways of aggregating the staff needed than simply having part time people on a single day or two. I'm sure many, possibly even DVC, have part time staff just for certain situations but anyone can do this if they want and have the need. I don't see that it has an impact on the appropriate expectations of room turnover though, you need to have the staff to get the job done without a lot of waste.
I will tell you that Marriott in HH has gone to importing for Summer from places like Jamaica for housekeeping. When we were in HH this summer, almost everyone we saw in restaurants, grocery stores, etc had a North Eastern European/Russian type accent so I'm guessing someone has imported them for purposes of filling the lower wage jobs.
Our issue was that we had traveled with a 6 month old and a 3 year old and had extra luggage for the little ones. I had called Bell Services to come and help with the luggage and we were waiting for them. At 11:00 on the nose, Mousekeeping knocked on the door. 
However, this gentleman ASKED if it was alright with us if he started stripping the beds. 
Since he had shown us this courtesy, we of course had no issues with it.
I have been told that all of my grocery bags go into a cooler, but would love some confirmation on that as no one has ever asked me what to do with which bags...
