I had my car over from Northern Ireland for most of first year, I was in DRA and had absolutely no trouble getting a permit, however I'm in John Burnet for this coming year so I'm not taking it as there is really no point! There was little point me taking it when I was in DRA, I never used it for going into town, it just made Morrisons/golf practice centre trips so much easier! I just make one of my parents take me over the sea instead, but I understand it would be hard if you don't have that luxury! I too have way too much stuff to take on a train or plane and I have an infinite amount of respect for people who do manage this!
Apparently there's free parking on the Scores, my mate who has a flat on market street for next year told me this but she could well be wrong, but anyway I know that that gets busy. However it would be useful for Sallies and maybe MaccyTs (but this has some (very limited) parking round it), I have no idea for Regs or Uni hall, I'm guessing Albany has parking, and for John Burnet you could probably use the big car parks near the science/management buliding right? They're free aren't they?! Obviously DRA/Fife Park has car parks, and I'm pretty sure New Hall and Melville to do, so it kind of depends where you end up. Sorry thats not much help! But as far as getting a permit goes you just e-mail the people, give them your name and registration number and they send one in the post! V. easy!
