Hello, The service I received by calling the Hyatt 1-800 number this week was positively mediocre. Both times, the rep said that it was going to cost me extra me to amalgamate two reservations so I wouldn't have to change rooms halfway through the stay. Thankfully, the front-desk clerk at the actual hotel (Hyatt McCormick Place) to whom I was transferred settled the problem at no extra charge. What is the problem with the switchboard? Do they not have access to the same comouter files? Dealing with the switchboard cost me 30 anger-filled minutes of my time, not a 5-star hotel experience. This may be my last time staring at Hyatt.
