This would be an unfortunate change, imo. Higher housekeeping standards was one of the things I really liked about SVN resorts compared to MVC resorts - hopefully they aren't taking that away.
I wonder if the destination club will be paying this fee every time they split a week into multiple reservations...
The policy has ALWAYS been that you only get a (free) mid-week tidy on stays of 7 or more nights, and generally a full clean after 7 nights. I believe that applies regardless the type of stay. If you want additional housekeeping on a shorter stay, you have to pay for it. That's not new.
What has changed is that they have gotten a little squirlier (in my experience) on the full clean after 7 nights, they may only do it if you ask them to, and you may have to ask them rather insistently. Personally, after a week I think the unit usually needs cleaning and I will insist that they do it if I'm staying longer.
The other thing that changed, for those who are enrolled in Abound, is that you no longer have to pay housekeeping fees if you make short stays in excess of the number of VOIs you own. So if you stay three nights on one stay and then four nights on another (and you own one week or one bundle of Flex points) you won't have to pay any housekeeping fees, where in the past you'd have had to pay a fee for the second stay.
