When we went to the open day last year, physiotherapy talk was in the David Ross Sports Centre, however the course is mainly taught in the hospital I believe, which is just over the road from the campus (a pedestrian bridge links the campus to the hospital), so it is pretty much all in one place really. It is a huge campus though. It's a very pretty and green campus. My daughter is starting at Nottingham for Physiotherapy in September!
I cannot help with places to stay as we are within driving distance so didnt have to arrange that. The campus is pretty close to the city centre and there are great transport links to the uni (tram).
Good luck with your open days and applications!
