Part 1. Definition
Classify the given hotel review based on the sentiment it expresses into two classes: negative and positive.
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 Hotel Allegro located in the Chicago Loop, provided my wife and I with one of the worst hotel experiences in recent memory. We ordered the weekend Liquid Therapy package 48 hours prior as noted on their website, but to our surprise when we arrived, our names were nowhere to be found in their system! No room, no accommodations at the restaurant, nothing had been prepared for us and apparently another couple had already reserved the last available slot. A weekend away turned into the weekend from hell when we were asked to take a smaller room than I originally booked, and never did they offer us a replacement dining option! I have a receipt and credit card statement that shows our reservations being made on time. We will never be staying here again.

negative
