i suggest visiting the Bethpage Golf Twitter feed @BethpageGolf. The staff has done a great job of posting information there this year and I expect them to do so from now on.
Definitely call the office tomorrow. Earlier the better.
I don't think so as I recall that tomorrow (9/13) is the Joe Namath annual charity event @ Bethpage. They usually have only one course open (likely Yellow) to the public as the event historically books all the other courses. You should call the pro shop in the morning.
Yes all courses are open The yellow, green and blue
