Classify the given hotel review based on the sentiment it expresses into two classes: negative and positive.

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.
Solution: positive
Why? Review writer likes the hotel. There are strong positive words like 'impeccable' and 'great'. Therefore it is classified as a positive review.

New input: I stayed two nights at the Hilton Chicago. That was the last time I will be staying there. When I arrived, I could not believe that the hotel did not offer free parking. They wanted at least $10. What am I paying for when I stay there for the night? The website also touted the clean linens. The room was clean and I believe the linens were clean. The problem was with all of the down pillows etc. Don't they know that people have allergies? I also later found out that this hotel allows pets. I think that this was another part of my symptoms. If you like a clean hotel without having allergy attacks I suggest you opt for somewhere else to stay. I did not like how they nickel and dimed me in the end for parking. Beware hidden costs. I will try somewhere else in the future. Not worth the money or the sneezing all night.

Solution:
negative
