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

Example 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.

Example Output: negative

Example Input: A friend highly recommended this hotel and we couldn't have been happier! It was wonderful ~ my husband and kids were already planning our next trip there before we had even left the hotel. The kids loved the goldfish in the room and thought the window seats were the best. 

Example Output: positive

Example Input: The Omni Chicago Hotel was a delight to stay in. The second you step into the place, it takes your breath away. It's very modern with an antique twist. The rooms are spacious and comfortable. They are clean. Every member of the staff was courteous and polite. Proud of their place of work. Happy to be there. You don't often see that. The room service was phenomenal. Visiting Chicago was amazing, and staying at the Omni Hotel made my visit that much better. The luxurious pools were an added plus as well. I also enjoyed the gym facilities. I will definitely be staying at the Omni Hotel on my next visit. 

Example Output:
positive
