1) Pretty sure theres no Ensuites, and yes there will be a form
2) 10min Walk
3) depends if its a college or uni one, lots of societies meet on the hill however will meet in town. However the route up the the hill colleges is all on a main road, well lit and always has people on, even up till 3am ish. also Durham is very safe
4) no idea
5) most colleges have lots of teams (for instance Collingwood football has A->G) there will generally be a team for you ability and commitment level and if not you can start one!
