I Know Warwick Uni rents it's student acoomodation out - and it's fantastic there - Cov is a great place if you talk to people and there are often lots of people around at the uni.

Biking I have often found dangerous - but as long as you take the opinion that anyone in a car won't see you and keep your eye on them - and don't go on motorways - you should be ok - good luck!

get yourself a cheap one man tent - thats prob the easiest way - then if you get really stuck you can see if you can stick it somewhere for the night (careful tho in case you're trespassing!)
