I have used the "guest of honor" for friends right after it was bookable (beginning of March 2015) and the HGP line in China knew what I was talking about. I received the confirmation e-mail (with extra note "CHANGE" and the person's name I gifted the stay to was mentioned. They stayed at a GH in China and all Diamond benefits were given/honored. GREAT! Issue: Recently made another "guest of Honor" reservation for my wife. She is HGP Platinum. For the same night made a point and cash reservation for myself as we were traveling with all our kids. So we had a total of 2 rooms. My points and cash shows up in my Hyatt account. My wife's does not! It does not show up in either one HGP account. So I cancel my stay and COMPLETELY forget that I had a "guest of Honor" reservation in her name. (my fault) My credit card got charged over 200$ for this "no show". (it had cost me 8000 HGP points originally) As we know the "guest of honor" is a benefit that was introduced in Feb. 2015. I am still learning to work with it. A problem with the "guest of Honor" I encountered is, 1.) that it can not be canceled online 2.) It does not show up in my Hyatt GP account under future reservations, nor in my wife's as at time of booking I am only ask for her name and credit card detail. (not e-mail address or HGP #) 3.) neither the one that books (me) nor the guest of honor received a Reservation Reminder e-mail. I have contacted the hotel now (where I have stayed several times before) and ask for a refund. I see how this goes.
