The hotel in general needs a major overhaul. The whole place is stuck in another era. The toilets in the guest rooms seemed like they came out of a public washroom. Every time a toilet flushed somewhere around me, I can hear it and feel the water pressure change during showers.

The WiFi was spotty at best. Throttling the WiFi so we had to pay to use Netflix or other streaming services didn't seem conducive to the amount we paid for our stay. I've stayed at competitor's high-end hotels rated similarly to this one, but Hyatt Regency O'Hare has yet to meet the standards a high-end hotel would normally meet.

The service during the event in the large banquet hall was the worse.
Food during the event was dry, lukewarm, and cold in the center. Terrible. I've had better food, even mass produced food such as the method used at your hotel, at similarly rated competitor's high-end hotels.

The wait-staff took away food and beverages that were barely touched and still being eaten. I had to constantly tell them the items on the table shouldn't be touched (beverages, full water bottles, food, etc.) It was as if they were mindless drones just looking for something on the tables to take.

They threw away items that were not provided or paid for by the hotel (i.e 3rd party deserts and one-of-a-kind, hand-crafted party favors). Simply put, YOU TRASHED FOOD AND ITEMS, THUS THE MONEY AND TIME SPENT ON THEM, THAT NEVER BELONGED TO YOU. In every event such as the one I attended, the courtesy to pack up the deserts was always given and standard service. I have NEVER experienced such neglect and inhospitality. Isn't being hospitable the whole point to your industry?!? You should be ashamed of the standard you instill on your wait-staff and chefs. It was so abhorrently neglectful, it almost seemed like a hostile joke. "Maybe all the stuff is going to come back out," I thought. But this joke was literally at the cost of your guests.

I would not come back to this hotel in it's current state or any 'improved' state, so I guess you don't have any incentive to improve your services. I feel terrible and sorry for any future guests who do business with you.
