maddy47 if you should be invited back again, I'd suggest that you offer to pay for a toilet pump out (about £15) at the end of your stay and then relax about the toilet arrangements!
I can't think of a much more off-putting experience. Such a shame! If you get the chance to spend time on a narrowboat again, I hope the toilet arrangements are satisfactory and you realise what an enjoyable break it can be.
