What is the difference between a “My Hyatt” profile on hyatt.com & “My Profile” on goldpassport.com?
All Hyatt Gold Passport members have one universal profile on goldpassport.com and hyatt.com called “My Profile” that includes all membership information, preferences, and interests. As a member, you do not need to create a separate “My Hyatt” profile. However, if you do not wish to become a member of Hyatt Gold Passport, a “My Hyatt” profile can be created to simplify the reservation process on hyatt.com and allow you to sign up to receive e-mail from Hyatt. If you are a Hyatt Gold Passport member and have already created a separate My Hyatt profile, you can merge it with your membership profile in order to access all of your profile information and preferences with a single login.
