It will be camping, we are not going into the house at all. It will be a tent, sleeping bags, one source of water and pooing into a hole in the ground lol! And no electricity, so gas stove and all that stuff. Not sure how one defines camping but that sounds like it to me.
If they let everyone into the house to use the facilities it would be a nightmare I expect, so no washing machine.
I don't even know the people so wouldn't ask anyway but I imagine if I used it then the other 100+ people would want to as well.
I could hand wash under a tap maybe?
