Because, as DVC found out with the 2020
point charts fail, who wrote the original POS gave owners a lot of rights and guarantees. It was a time when Timeshare was a synonym of Scam and a big brand like Disney put a lot of reputation on the line creating their own timeshare. They're changing that and they're aligning to "industry standards". I may be mistaken, but RIV POS also includes the possibility to reallocate points across Units and the CFW POS explicitly say that points could be reallocated even across different resorts belonging to the same Use Plan (if there'll ever be others). That's why I wouldn't touch CFW with a bargepole, not only it has high MF; it might even have high point charts in the future.
Full disclaimer: I don't have a strong opinion about the 2011 rule and if it's the only relevant or not. I haven't studied all the docs enough.
What I am worried about is that DVC might use the issues with commercial renting to take away rights we currently have. I bet DVC would love if members would stop any form of renting, if anything because it would probably result in more breakage.
