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

Example input: 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.
Example output: positive
Example explanation: Review writer likes the hotel. There are strong positive words like 'impeccable' and 'great'. Therefore it is classified as a positive review.
Q: I stayed at the Hilton Chicago during a recent business trip. I elected to go with their Executive Suite upgrade. All I can say is, "What upgrade?" It's barely anything above what you get normally. And for the price I paid, I was expecting much better acommodations. Because I arrived around 10:30 the night I checked in (delayed flight) I did not get the concierge service as it stops at 10. I find that an odd hour to stop a service like that especially when you're expecting a guest who has not checked in yet. Beyond that, it took them 20 minutes to get me into my room. First it was a room mix-up, then it was a missing key card. That was extremely frustrating as I was tired and I had a presentation to give the next morning. Speaking of the next morning, the complimentary breakfast was a joke. When I just want a stale muffin and a bad cup of coffee for breakfast, I'll stay at the next Super 8 I find. And the wireless internet in the room that you actually have to pay for on top of everything else was a horrible connection with angonizingly slow speed. I will not be staying at the Hilton Chicago every again even though I frequent Chicago. This tops out my list of horrible hotel experiences by a long shot.

A:
negative
