In the end though, the spaces will still be full they will just be full longer. I suppose the argument is this. "Since there is NO parking (as you have said) in the area why should 1 person be able to "hog" the spots when you have a whole building who should have fair access to the limited parking."
Now my question to you is... is the Visitor parking constantly full? If there are readily available spots for 75% of the time or more (empty) then I see no reason NOT to extend the amount of time per spot. However, IF the spots are full 75% of the time then a shortened time frame means more people have access to a spot more often during the day. Sorry to play devils advocate here but just trying to see both sides of the coin.
Another thing to possibly bring up is to possibly have the 4 hour parking from 9am to 9pm. This would address the issue of people spending the night or having to leave a car due to drinking or whatever.

Berz out.
