Before the approach, did you brief what you would do in event of nav aid/approach aid failure? You cannot consider using a map if you haven't briefed it!!!!!
If not - carry out a missed approach, re-brief and try again with the higher minimas.
If you did, then surely you were the sort to brief for every eventuality so no snags, it was covered in the brief:-)
(Tongue now out of cheek)
If you have required visual references why would you want to go and do it all again?
Were you single-pilot? Dual controls? Company SOPs?
