One of the things that the caving community seems to be trying hard to drive is increasing the number of younger cavers as they are our future. I suspect if you took away the stomp/party aspect, then you'd lose a lot of the younger cavers who choose to come now... We can't please everyone all the time, but i think it's important to encourage the younger generation to turn up and they are usually also the ones with the least money so keeping the stomp as part of the general entry fee and hence 'free' is likely to matter to them more, although i bet they spend far more than the stomp would have cost at the bar!
I'm one of those people like cavegirl99 describes below who does like to dip into the stomp and would like to have a boogie here and there over the evening, but not enough to bother to pay for it outside of the general admission costs of the event as for me the spare time outside of lectures is about making the most of HE to catch up chatting with people i don't see often so don't want to devote all evening to the stomp. I can understand from reading the above that some cavers perhaps don't want the noise of the stomp or all the drunks about at all, but what would those that don't want the stomp/piss up prefer to do on the Saturday evening? I thought the Monmouth venue was excellent for having the balcony area a little away from the band/bar allowing those wanting a bit more quiet to chat to do so while keeping the entertainment close at hand.
