Part 2. Example
I stayed at the Hilton Chicago for my cousins wedding. The service was impeccable. Not only was the staff attentive, they were respectful and careful not to interrupt the guests or make themselves known when serving dinner. I had the chicken wellington and it was to die for! The chicken was perfect and moist but the pastry crust was flaky and crispy. They even had Pakistani dinner options for some of the guests. The amenities were great, and after an open bar the night before, the Mimosas and brunch buffet couldn't have been better! I would love to have my wedding there.

Part 3. Exercise
When we were stranded in Chicago for two days since our flight home was canceled, our airline put us in touch with hotels.com who found us the room at the Sheraton Towers. After a long and frustrating day that ended up with us still in Chicago, arriving at the Sheraton was a joy. The entire staff was wonderful. The bell staff was great helping us (finally) let go of the heavy bags, Jonathan at check in was very helpful and had us in a room which he upgraded for us in no time. We enjoyed the location and the facilities of this property during our unexpected stay and would highly recommend this location to others. We can't say enough about the staff. If we are in Chicago in the future we will definitely return here!
