I'm mostly interested in why the OP felt s/he needed to leave the Stamford property earlier than planned due to no hot water and head straight for the pre-reserved room at the Sheraton NY? I don't follow how no hot water after 10am on the morning that you're planning to leave could cause you to need to bolt from the property.

Just how much longer would the OP have remained at the Stamford location if it had hot water and why?

I'm with Idsant on the insult thing. There was no call for that remark and it won't serve you well. The Sheraton Promise program stopped about two years back and was a program designed to be a start/stop program to help change attitudes and perceptions about the Sheraton brand. One has no choice but to surmise from your tone in your original post that you presented some attitude in your encounter with the front desk -- that's never the best way.

If you had a legitimate issue that was complicated by the no hot water reality, then was the time to outline your problem with the front desk and seek resolution.

From where I'm sitting, this seems like a tempest in a teapot.
