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

Input: Consider Input: My family booked five nitghts at the Omni Chicago for our upcoming spring break. We took advantage of a pre-paid, non-cancellable offer. We subsequently received a "Bed & Breakfast" offer via email and immediately called the hotel to inquire whether we could switch our reservation (same dates, different offer). We called the 800' number and the customer services representative was so obnoxiously condescending and ignorant, we simply hung up. We had been looking forward to our vacation, but now I am not sure I made the right choice with this hotel. I should have paid closer attention to the reviews - the Ritz, the Four Seasons, and the Peninsula would have never treated us this way. I will post again after our stay on April 17th.

Output: negative

Input: Consider Input: We travel to Chicago frequently and have stayed in many of the hotels downtown. We were excited to try the Swissotel, but left disappointed. The actual hotel and rooms were very nice with amazing views, the staff was extremely rude. The man that checked us in was on the phone and did not acknowledge us until he was done with his phone call. He then did not say more than five words, which were "I need a credit card". The lobby bar had fireplaces and was very cozy. The hotel information said it closed at 2am so we came back to hotel at 1230am for a "night cap", that was last call. That was fine for us, but the bar was full and many people were coming back from their night wanting a "night cap" but did not make last call. Our night ended listening to many unhappy people complaining and receiving no sympathy from the employees. There are many places to stay in the area that are just as nice or nicer, no need to stay at the Swissotel again. Definitely don't stay if you're looking for a romantic weekend away, the employees will ruin your experience from the second you walk in the door.

Output: negative

Input: Consider Input: Sofitel not-so-luxury Hotels I recently checked out from a short stay at the chicago water tower. I originally planned to stay for a week but as my business was concluded after only 3 days I decided I had had my share of the water tower. Simply put it offered no reasons to stay. The Hotel is quite lovely and elegantly dressed to impress, but little more is put forth to sway the more acquainted crowed. The First night was a spectacle meal and there was quite a crowd, I think for the weekend. The next night the food was only mediocre and the third when I orderd room service I had to call twice. Even if you don't care about the food I think you would be wise to think twice about your stay if you have the choice. They put on quite a show, but that is all and when the show ended I was still hungry for more and there was no more to be found.
