I have worked for several years in tourism and don't think I have come across anyone as rude as the host of this campsite. He swore at the 'bloody Europeans' on our mine tour and asked 'Do you even speak English?' before launching into a rant about how much he dislikes children. The underground camping area is like an echo chamber and every sound is magnified which is most unpleasant if anyone snores or there are any unsettled babies. We stayed in July and it was several degrees warmer underground but next time I'd opt for the cold!
