Student parking on campus?

I graduated last year, so may be out of date, but my experience was:
- it was tricky to park anywhere unless you were on campus early (<0900)
- everywhere was pay and display or pay on exit
- there was a local resident permit scheme around the back of tescos
- tecsos started putting up cameras limiting you to a couple of hours parking

Overnight parking, I would suggest, is nearly impossible without paying a small fortune (although I don't know how tightly enforced the last two points are).
With the pay and display option on campus, it was worth not buying a ticket and taking the fine when they caught you - again this may have changed.

If you have a medical condition, you can get a permit which allows you free overnight parking. Outside of that, you're unlikely to have much luck. Bear in mind that 'medical condition' can be pretty broad, and not actually something that would require you to have a car.

Nope, no medical condition...although I do work at residential homes nearby and that requires transport in case of emergencies but that's about it really!

You can park overnight in the Sports Centre car park near Tocil, and on weekends it's free too. If you get an exec position on a society you can get a free parking pass too.
