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

Example Input: I arrived and my friends were already there and visiting a nearby art gallery. They put my name on the reservation and told me to get a key from the front desk when I arrived. The front desk staff gave me the key to my room and I put my stuff away and went to meet the group. We returned late that night and I soon realized the room that my friends were in was not the room that I placed my stuff in that afternoon. We went to speak with the front desk. We were met with "We can't do anything about that right now due to the hour. We will not disrupt the guest staying in the room you say you left your stuff in." Unacceptable!!! My $1500 laptop and all of the things I brought with me were in that room! Not my mistake! FINALLY, after arguing with the head of security for about 30 minutes, they knocked on the door of the room I had left my belongings in and a lady answered. She was upset and stated she had security take the items from her room in the afternoon. All of my belongings were recovered in the security room; however, all of this hullabaloo could have been avoided had they communicated about the situation! Terrible, terrible customer service. They sent up an apology letter, champagne, and chocolate covered strawberries to the room. Although I was appreciative of the gesture, it still does not excuse the fact that they argued and continued to say "We can't do anything about it."

Example Output: negative

Example Input: Stayed in April for two nights. I hesitated selecting the Sheraton becaue I had a very poor stay there earlier this year. As far as I'm concerned, that's two strikes and I won't give them a chance at # three. Doormen wouldn't help on arrival, huge line at c/i, lousy room, malfunctioning remote, unresponsive staff, and incorrect bill. If you want to be close to Michigan Ave, try the Westin or Intercontinental and spare yourself the problems. I don't understand why certain places never improve. Is it that tough to properly train a staff?

Example Output: negative

Example Input: Wow! Loved the Ambassador East Hotel in Chicago! It was so close to all the great sights of Chicago like Navy Pier, Lake Michigan, and all the fabulous dining. The hotel was very classy and the rooms were furnished in a traditional, but cozy manner. The entire family loved it, even the dog...because they are also pet friendly at the Ambassador East Hotel! We loved the restaurant there, the Pump Room was great, something to please even the pickiest of our eaters. We were there on a family get-away, but asked to see a larger "suite". The suites were gorgeous. I can't wait to tell our friends about this place! Our next business trip to Chicago, we are booking at this hotel. They have the perfect conference rooms and we LOVE the service! We are definitely coming back!
