I did a points transfer online to Hyatt Gold Passport at the Club Rewards site. It was more complex than necessary as I had to add four separate rewards to my cart to get the desired number of GP points. When I checked out I had to enter my GP account number and date of birth four separate times, once for each reward. After that worked it didn't like my mailing address which had been pre-populated with my zip+4+2 which DC uses to send my statements.
So after all was fixed and the redemption processed I got an email stating it would take 2 to 6 weeks for the points to hit my GP account.
I'll let you know when that occurs.
