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.
Answer: positive

Part 3. Exercise
For starters, I had trouble reaching the front desk. Every time I called it would ring endlessly! When finally I did reach someone, she was snooty, impolite, and altogether unhelpful. Being from the south and not knowing anything about Chicago I was hoping the staff would have been more helpful in guiding me around such a large metropolitan area. As I was there on business, I was really looking forward to the Wi-Fi access so that my business activity would go uninterrupted. Unfortunately, this was not the case. After multiple log in attempts I ended up going to a local "internet bar." As attractive as the rooms and the hotel itself were, the complete and utter lack of service and delivering up to expectations was disappointing.

Answer:
negative
