I hope someone has been fired over this IT cluster.
Just tried to go to the website (didn't even try logging in) and surprise surprise:
Hyatt.com, GoldPassport.com and other related sites are currently down for maintenance. We apologize for this inconvenience and are working hard to get everything in order and back online. Please come back soon!
Unbelievable - how is this still happening despite going offline for 4 days in December and numerous small outages since?
