I must admit, if I'd diverted in the middle of the night like that, I'd probably cut my losses and stop the night - and have on a couple of occasions (usually due to weather, so a more straightforward decision).
But, of the three aeroplanes that I routinely fly for myself, two of them I know well enough that I'd be content making that sort of decision on my own engine without resorting to outside assistance.
Which basically means, it depends.
