So I joined Hyatt GP this past week and made a reservation at HP. I checked in using the kiosk and it asked me to join GP even though my reservation had the GP number already. I then wanted to verify that my stay will be credited even though I had put in my UA number to get the mileage bonuses. The agent showed me the screen and had a 5 digit member ID instead of my GP number. Should I be worried about the stay not being credited for FFP?
