The first time his father took a turn and was in the hospital, this morning his son was in an accident.

Well it sounds to me he's either lying and a terrible person to drag his family into it just to excuse a cancellation OR he really is having terrible terrible luck lately.

I'd just say that maybe it's not the best time for him to enter into a sugar relationship, wish him well, and tell him I'm proceeding with other arrangements.

Seriously, I fucked with a guy who's wife had a miscarriage while he was frankly running around cheating on her with me & you don't want the drama and guilt of all this in your life. What if his son really is in the hospital and goes into shock while he's off in a hotel with you? Or if he misses his father dying in the hospital because he had to be off somewhere tending to you? Not trying to guilt you, just saying reality is stranger than fiction and I still to this day wonder if the woman in my case had a miscarriage (she was very pregnant) because she found evidence of her husband cheating. Don't play when it gets medical.

A real relationship can overcome these things through time and therapy imo but if this is a financial thing for you, this guy is a walking "Don't even fucking try it" in my book.
