What a fantastic surprise. I have stayed in many hotels in the Windy City. I checked out of the W on Lake Shore due to their construction noise and checked into the Park Hyatt. Staff was uber nice and professional, rooms tasteful and more than luxurious. Food at hotel could not be beat. I have already booked two more reservations and looking for excuses to go to Chicago to be pampered at this wonderful hotel. Great location but the staff could not be better!!!
