When did the rules change? I rarely do this but the last time I did (2023), I made the reservation on points and then promptly called the hotel to give them the name of the person checking in. They had zero issue with it. And my family member had zero issue with the reservation. It was a last minute, flight cancelled situation and I'd rather just book a room for my family member than have them stand in a 3 hour line to get told by the airline CS that weather doesn't cover the hotel.
I'm all for following the new process if there is one. But my assumption (we know what that means) is I could still book a reservation and call the hotel to give them the name of the person checking in and not have any issues. I didn't trust the Ambassador line to do anything right and I sure as heck don't trust whoever answers the Titanium line these days.
