£30 is probably the cheapest nightly rate you'll get for a B&B - don't expect it to be especially nice at such a low price and be lacking in facilities - you probably won't have a TV in your room and may have to share a bathroom with other people on your floor. For £10 you could possibly get a bed in a youth hostel, but its likely you'll be sharing a room with other people. To get such a cheap rate you'd usually need to be a member of YHA or similar which has a cost involved.
If you want to camp - you can buy a reasonable tent for £20 from Wilkos or Argos. If you look after it you can use it for many years.
Nobody would be able to afford to run it and make a profit on less than that. A camp site, of course, doesn't have to provide you with a building to stay in or pay business rates on the value of the building.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
