We must have run into much nicer people in October. My mom had a knee-brace on, and each and every time the bus was standing-room only, someone offered her a seat.
I know that this is easy to say but hard to do. But if you feel that your personal safety is put at risk when you board a bus, then don't board. Go grab a taxi, wait for another bus, or go rent a car. They have an on-site rental place on the Boardwalk. Don't rely on total strangers for your well-being, take care of yourself.
My mom was fortunate that people gave up their seats for her, but we were not worried about her standing, she would have been ok. And I actually did give renting a car some thought before our vacation, and if it would have turned into a problem, I would have gotten one. We never got on a bus with the expectation that someone would give her a seat. We were just grateful when they did.
