You are really looking at the wrong things. Housekeeping and room service are incidentals in
DVC rentals. You should look at the basics to be sure a
DVC rental is right for your situation.
The biggest difference between a
DVC rental and a regular hotel reservation is that there can be severe penalties for changes in plans. The best way to consider any DVC rental is that it is unchangeable and non-cancelable. That's not always true, but it's the best mindset to have.
Also, DVC rentals involve a lot of trust and are not without risk. You might want to look at this thread, which offers some advice to prospective renters:

[ETA: The vast majority of DVC rentals go through without a hitch and provide the families renting reservations with a deluxe vacation at a big discount. You just need to be sure this kind of a transaction meets your needs.
It doesn't work well for last-minute trips; in fact, many savvy DVC owners won't even consider renting a ressie for a last minute trip.
But if you are comfortable with the process and trust required, and if you can make plans several months in advance
and stick to them, you may find a significant benefit to renting a DVC vacation.]
