We had a long day of trip cancellations and trying to find flights home and ended up having to spend the night in Chicago so we chose the Hyatt Place. We called the hotel to confirm how to access the shuttle and after being in the airport for many hours and retrieving our misplaced luggage, we went outside in the freezing temperature to catch the shuttle. As we were making our way across the roadway to the pick up spot, we saw the shuttle driving up. We as a group of 6 began waving at the driver. He made eye contact with our group several times and continued by us and drove away without shipping at the designated spot at all. We immediately called the hotel, who contacted the driver, and then got back on the phone with us to say he wouldn't come back for another 40 minutes. When he finally did arrive, he did not speak to us at all. Not one word of hello, my apologies, nothing.
When we got to the hotel, the front desk clerk apologized, but we were offered nothing more.
On a note of good service... The driver from the Marriot Hotel actually came into the airport doors to call out to see if anyone needed the Marriot Shuttle as most people would not be able to stand out in the freezing temperatures to wait.
Hotel in itself was fine. Food choices are extremely limited, but the bar tender was very pleasant.
