>>262653ive done it, we brought in some tents and sleeping bags (didnt want mice and spiders spooning us) only complaint i had was the cold when your awake the 50~60f temp is fine but after a few hours of sleeping you get cold as fuck since the sand sucks your body heat through the floor of the tent. its pretty weird waking up and opening your eyes and not being able to tell if you actually opened them. other than that its worth doing it just for the experience.
pic is from the cave looking down one of the main tunnels.
