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

Input: Consider Input: Here are my experiences: - Had three rooms reserved, when checked in we were charged 2 different rates for the rooms - screwed up initial room assignments, gave us a room that was not even cleaned yet when we checked in - Could not get us new keys to a different room without great difficulty (we had to go to the front desk because bell staff went to the wrong room to give us new keys) - In room guide says pool in on the 8th floor and signs say it is on the 7th - could not get to the pool from the 14th floor without going all the way down to the lobby and then had to go to the 7th floor and take the stairs to the 8th - When we checked in we had the front desk staff go over which credit cards were assigned to which room. - When we received our bills, the credit card assignments were still wrong. I stay at "economy" hotels a lot and I have not even come close to having this many problems with a hotel until this one. This hotel should do Chicago a service and just close its doors. Due to this experience, I will never stay downtown again to deal with overpriced hotels with poor service and surrounding business that are just as bad.

Output: negative

Input: Consider Input: Hard Rock Hotel is a must to visit. No matter what city your in Hard Rock Hotel is the place to stay. Filled with fun and unique traits to the rooms and dining. This Hotel is the place to be. Great views in every location, especially Chicago. The service is incredible along with the food and decor. The Hotel staff will help you feel right at home, no BETTER than home :)

Output: positive

Input: Consider Input: Apart from the location, great, but it stops there. Upon check-in, I was informed I would have a queen bed. I asked for a king size bed, and I was told there would be a charge for going up to a king. GIVE ME A BREAK, a surcharge for going from a queen to a king. When I got up to the room, it was like a oven. I could not get the air to work and needed to call twice before getting service. Everything in the room had a charge associated to it, even down to the coffee, $1.00. Now what's up with that? I was very disappointed in the size of the bathroom. Very small. I have stayed there twice and with so many other options, I feel this will be my last.
Output: negative
