Traveling between the campuses won't be much of an issue as there are regular buses running (meant to be every 15 minutes).From my experience, you can easily live without a car in Notts. Also, what I have noticed is that there usually tend to be more international students in the halls at jubilee, so you might want to factor that in. As far as I remember if you choose catered, then you are just assigned a hall which you can later get changed if you want.
I would suggest going with UP regardless of where your classes are. It is so much better for social life, also all halls on university campus are catered. Society events pretty much take place there only so it is easier to get involved in uni life If you want self-catered then you live off campus (I did this and my experience wasn't so good), although Raleigh & St Peters are just 10-15 mins walk from jubilee and broadgate is a 10 min walk from UP. Broadgate is in Beeston, which I personally find to be a bit of a dull area but you will be surrounded by students so should be fine. If you choose Raleigh or St Peters then you have a Lidl, Dominoes, Tesco really nearby and is quite handy to run down to get everyday stuff.
