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 Sofitel Chicago Water Tower was horrible. The first tip off that this would be a bad experience is when we had called ahead to make sure it was OK to check in after hours and that a concierge would be available when we arrived only to find out that they didn't even have a record of our reservation. After much inappropriate arguing, they found our reservation and we were assured all would be fine. When we checked in we got a dirty room without any working wifi or TV. It took a few calls to get fresh towels and for them to turn the heat on so we could sleep comfortably. The next day we called to get our complimentary room service that most decent hotels provide free and they had no records of us even checking in. A quick check with the credit card company had they charge already pending in the wrong amount. We finally left in disgust and got a much better hotel, the FancyPants Hotel and Suits with complementary airport shuttle and award winning preferred member rewards club. Overall, the service at the Sofitel was rude, rooms were unsatisfactory, restaurant sub-par, not well kept up or clean. In the future I would never stay there again and wold definitely pick a more reputable hotel with a proven track record, like the FancyPants Hotel and suits, my personal favorite.
