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
For the amount of money per night that the Millennium Knickerbocker Hotel charges, one would at least expect a room with a working bathroom. The toilet wouldn't flush, the sink dripped and the towels were rough and cheap looking. When I called the front desk to ask for maintenance on the sink and toilet, the staff were indifferent. It was over an hour before anyone arrived to fix the bathroom fixtures, and when they did arrive they were unable to stop the drip in the sink. All in all, I was disappointed with my stay.

Answer:
negative
