I wanted to share my experience on trying to transfer a room reservation at Universal to the Chase Cruise and Tours Department.
I booked an AP rate on the Universal website for $265 a night versus the regular rate of $374 (traveling in August). I had to put a one night deposit down but felt that was worth it to get the lower rate and then wanted to transfer to Chase and pay the balance with UR's. I called the Chase Cruise and Tours number listed on the reddit thread, 855-234-2542. The first rep I spoke with said it could not be done. Time to HUCA! Second time I got Terrence, at extension 8118. He said it could be done, it was just a slightly longer process than transferring from Disney. He put me on hold and called over to Universal. He then came back and said I needed to call the "rooms only" line 800-232-7827, and give them permission to transfer the reservation to the T.A. "Loyalty Travel". That went smoothly and I called Terrence back to let him know it was done and he could call them again.
This is where we ran into an issue. He was unable to take over the reservation because, according to Universal, I only had a "placeholder" on the rate. My balance isn't due until I check-in, at which time I need to show my annual pass to confirm the rate. If I had booked under the regular rate, it could transfer. However, I don't see why anyone would want to do that. if I were paying the regular rate, I could just book on the portal myself and not have to jump through all these hoops! Terrence did suggest I cancel my booking with Universal and he could try to book the AP rate if it is showing up and I call him. That rate isn't showing up anymore for the times I can go. I'll have to see if my two rooms go back into AP rate inventory after I cancel. I'm pretty much expecting to book with points at the regular rate though.
Just figured I would share my experience in case this helps anyone!
