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
The Millennium Knickerbocker Hotel has seen better days. I had fond memories of staying there when it was considered the finest hotel. I booked a room to celebrate a special occasion and found a highly-priced, not so great property. I had to look at five suites before I found one where the upholstered furniture was to my liking, some of the other rooms carpet was not clean, the refrigerator was dripping water, and the balcony was littered with cigarette butts. I finally settled for a room, only because the bellman was friendly and apologetic but as over priced as it was I should have turned around and walked out. I sent a letter to the management when I returned home, but it had been a month and I never received an answer. There are plenty of other places to spend your money. Don't leave it at this hotel.

Answer:
negative
