Whenever we’ve used points for hotel space (not at Aulani but at all three of the California hotels), we’ve always received daily housekeeping like any other hotel guest.
It’s only when you book DVC Villa space that you don’t get daily housekeeping.
I think there may be a bit of confusion, if you are a dvc owner trading out into other hotels you would get housekeeping.
If you rent DVC points and happen to be fortunate to get one of the eight hotel rooms at Aulani vs. studio/1 bed/2bed/grand villa, it is consider part of DVC and you do not get daily housekeeping.
