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
I only stayed out with my boyfriend for one night, however enjoyed my stay. The staff was friendly, the room was nice and clean, the hallways and ballrooms etc were elegant. Room service was quick and had good options to choose from that actually tasted great. The staff was able to extend our check out time for an extra 1-2 hours without an extra charge to the room. Great location too! Walking distance from the Art Museum, Millennium Park, Grant Park (right across the street) and a quick cab ride to McCormick Place. If I were in the city again I would love to stay there again.

positive
