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

Let me give you an example: I stayed at the Hilton Chicago for my cousins wedding. The service was impeccable. Not only was the staff attentive, they were respectful and careful not to interrupt the guests or make themselves known when serving dinner. I had the chicken wellington and it was to die for! The chicken was perfect and moist but the pastry crust was flaky and crispy. They even had Pakistani dinner options for some of the guests. The amenities were great, and after an open bar the night before, the Mimosas and brunch buffet couldn't have been better! I would love to have my wedding there.
The answer to this example can be: positive
Here is why: Review writer likes the hotel. There are strong positive words like 'impeccable' and 'great'. Therefore it is classified as a positive review.

OK. solve this:
If you have not tried the Millennium Knickerbocker for a stay in Chicago, do it now! We have stayed (and enjoyed) at the Drake, Intercontinental and others, but we always now come back to the Knickerbocker. Why? If "Charlie" the doorman is on duty and you pull up, he will welcome you. He'll probably ask your name. Why? Because he wants to call you by your name every time he will see you during your visit. Somehow he even lets the other employees know your name and all of a sudden, doorman, receptionist, bellman, waiter are referring to you by name. The employees are what makes this hotel. Yes, it has everything to offer like all hotels, but the others don't have the fine people (including the cleaning staff) these folks have. Try it, you will like it. We look forward to our next visit already... 

Answer:
positive
