This reminds me of something that has concerned me lately, quite a few student members of my club this year, and not just the new ones, have seemed unwilling to go anywhere new without either a survey or someone who "knows the way" and trips to Devon and Derbyshire for next year are planned "as long as someone knows the way". What happened to the spirit of adventure?!
Pah, while I may have obsessively constructed my laminated survey to OFD, I haven't used it yet and the trips where I've gone in without someone who knows the way have been by far the best and most satisfying. My survey will remain a reference to help me get to parts of the cave I really want to see, like OFD3. I'm rarely that excited in a cave when all I'm doing is following someone's bum instead of finding my own way...although it probably depends whose bum it is...
