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
When we stayed at the Millennium Knickerbocker Hotel in Chicago, we had one of the worst visits i have ever experienced. Our room was not ready right away so we had to wait about an hour in the lobby. And finally when we made it to our room we found a moldy shower and a dirty floor. The room service took about an hours and a half to come to the room and she we went to the pool that day, it was so crowded there was no room to sit on the side. Our experience was definitely not a pleasant one. To make matters even worse, we were billed twice for our room which my husband luckily caught before we left. I am never coming back to Millennium Knickerbocker Hotel.
