Not owned by Wyndham at all. This is a little complicated. In the beginning...
Strand Capital Group built Anderson Club. They sold units as wholly owned condos -- you can still buy them today ($233K to $450K on their website). However, as sales lagged, they partnered with HGVC to unload half their units. Today, their website says...
"The project consists of 172 Hilton Grand Vacation timeshare units and 132 rental condominiums. On-site project management is provided by Hilton Grand Vacations." The Strand-units not sold to HGVC are rented thru Oceana -- a Wyndham TS rental service.
----------------------------------
This is similar to other projects (Elara, Trump, Marbrisa...) where HGVC buys part of a struggling condo/TS project, spruces up the place, sticks its logo on stuff, and acts like it was theirs all along... kind'a like when the Russians took over Crimea, but with $$, not unmarked troops.
