Input: Consider Input: I called the reservations line to book a room at the beginning of December 2012 for a rate with a local corporation. When I first made the reservation I did not get an e-mail confirmation. I had to call again to get the e-mail and then saw that I was booked in a handicapped accessible room which i did not need as there was me, my wife and three year old. I called the reservation line and asked for a regular room which they said was impossible at the rate I was at, however for ten dollars more I can upgrade to a regular room. I then asked what if a disabled person needs the room and he said he could not help me. i told them to cancel the room. based on the reservation experience, I did not want to run into anymore trouble at this hotel.

Output: negative

Input: Consider Input: went to chicago for a week in may, decided to be good to ourselves and stay in the hilton, we were not disapointed. perhaps it was becuse there were quite a few conventions going on and a lot of people were only staying 1 or 2 nights but we got upgraged to exceutive level. we had 2 double beds with a bathroom each. they beds and pillows were too die for, so so comfy ant the end of a day when we seemed to have walked for miles. all the staff were very helpful. a lot of guests seemed to ignore the staff especially the chamber maids who they seemed to think they were in their way so perhaps that why some people felt these people were rude or unhelpful. about 2 blocks away on Harrison is a cafe called "Orange" which you have to make the only place you will have breakfast, the cafe and the staff are suberb. expect a 15 min wait on a sat & sun morning.

Output: positive

Input: Consider Input: Had a week long stay at the Hilton on south Michigan while attending a meeting. The hotel has some elegance in the lobby, meeting rooms and lounges - the hotel rooms could definitely use updating. I would definitely say that for the price of a room here - the rooms should be top notch. My car was misplaced during valet parking, our reservations were messed up, hotel staff showed up repeatedly throughout the week at our door with items (room service, a new coffee pot, laundry) that wasn't ours. I would not stay at this property again. There are much better places for the money in close proximity to Michigan Ave. It is a very big hotel and at times it felt like we were staying at Faulty Towers.
