I heard today that rebranding will start mid Jan 2022, 10 properties rebranded as the new HVC with others added every month as required renovations complete. Orlando Grande Villas just upgraded building A and will continue with other buildings. CYPRESS POINTE gets elevators 2024 so no rebranding until that's done.
4 resorts will go to the higher end HGCV - Cabo, Orlando Mystic Dunes, Kaanapali, Poipu. My guess is that HGVC will rebrand Mystic Dunes 1st as their annual LPGA golf tourney comes soon (Jan 20-23) and they've rebranded the tournament and the $1 million "tent" for music- dining- cigar lounge needs lead time to put up. Hilton doesn't have a suitable resort in Orlando other than perhaps Le Soleil which might have room.
