I will say that I have grown an exponentially more negative view of Manhattan in my most recent visits. My company has a deal with two Manhattan hotels which both happen to be in or around Times Square. Getting around by foot, even just two or three blocks, makes me want to Cantona people every 8 seconds. Between all of the annoying paddlers, the overcrowded sidewalks, and the even more apparent abandonment of any traffic laws by drivers or pedestrians, I can say that Times Square has absolute crap. It used to be tolerable because it's still got a lot going for it, but it has been diminished.
We've held 3 of our last four retreat/sales pitches in DC or Boston, when they were all previously held in NYC. That's 10-12 hotel rooms for two nights per trip, simply because our clients and staff just get so frustrated in Times Square that it works against us instead of for us like it once did. Judging by what seems to be noticeable lower hotel rates, i'd imagine this is a growing trend (although Airbnb may be the main driver of this).
To sum it up, Times Square has become much less enjoyable for me as a tourist and business traveler since this mayor has taken office.
Sorry to continue this political derail (I hate when politics gets involved in a soccer related discussion, but because the mayor is such a major piece of the stadium puzzle, I guess it's mostly relevant here)
