November 22 appears to be switchover date
Just logged in today to check my reservation for November 27. Didn't know they were changing owners until now. November 22 appears to be switchover date. As previously noted reservation states it will be honored but no points earning. Not sure I want to risk paying for breakfast or being denied lounge access so I may switch hotels.
Edit: Just noticed they are still accepting reservations on the Hilton site for dates past November 22 including points + cash bookings. Is this typical or just the Hilton booking engine has not been updated?
