Definition: Classify the given hotel review based on the sentiment it expresses into two classes: negative and positive.
Input: Don't stay here if you take peace in knowing you have a reservation. About 3 months ago, we booked a room here for our wedding night (which is in less than 2 weeks). My fiance called last week to confirm the room and everything was great until today when they called to bump us to another hotel - no upgrades, no discounts. Apparently it is my problem that their manager can't manage the convention schedule. I don't even want to stay at another Kimpton Hotel because I don't find their reservation system reliable. Unfortunately, due to the conference, there isn't any other place to stay.

Output:
negative
