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
I recently stayed at the Fairmont Chicago Millennium Park hotel, and it was one of the absolute worse travel experiences that I ever had. One of the main reasons why I had originally booked my stay at the Fairmont was because the property offered special, "pure" rooms and suites that are supposed to be hypoallergenic. Because I suffer from extreme allergies -- and I really hate the thought of a less-than-pristine hotel room -- I was happy to pay extra for a room that was supposed to be specially designed for guests with environmental sensitivities. I'll tell you this right now -- save your money. When I got to my room, I immediately detected the distinct smells of cigarette smoke and mold. To add to the gross factor, I took a look around and noticed dust on the lamps and light fixtures as well as dirt on the carpet. The comforter on the bed looked messy as well -- as if someone had recently used the bed and then hastily threw the comforter back over it. There was no way I was going to stay in this room, so I made my way back to the check-in desk and politely informed them of the problems with my room. The woman at the front desk told me there were no other rooms available and it was only after we practically got into a yelling match that she grudgingly started typing away at her computer. After making me wait for another twenty minutes, she finally informed me that they could put me in another room, but it would be a four hour wait. Four hours! It was absolutely ridiculous. No hotel -- much less one that constantly touts some sort of promise of superior customer service -- should ever treat any of its customers this way. I do not recommend the Fairmont nor will I ever stay there again.

negative
