How Do I Negotiate?

First rule of haggling: always try your best to do it in person. It's not as effective if you do it over email or on the phone. You need to look them in the eye and gauge what kind of body signals are being given off.

I recently tried to extend a late room checkout over the phone but failed to obtain one past noon. Then I went down to the front desk and scored a no-fee late checkout time of 4 pm.
