Hello! I note you've amended this event to say its probably cancelled due to a lack of interest.
I'm not local so can't help anyway but I wouldn't worry too much if nobody else is able to. As cavers you'll probably find the rope work is as straightforward as it comes presuming you're all SRT competent and the route is fairly linear so finding your way shouldn't be a problem as long as you take a survey and swat up beforehand.
