Best bit of advice I got was when I was looking at Uni's the first time round in the UK nearly 20 years ago now...
Don't bother getting catered halls - most student's won't make it for the first (normal person's) meal of the day - they'll either be running late or it won't be served at a time that is convenient to them.
Based on my experiences here in Aus (which is quite different to the UK set up) the following observations apply:
-Find out where the international students tend to go - they're likely to be a big competitor to domestic students for accommodation. Where I am based, the internationals all tend to be in one accommodation option or in town rentals.
-Find out if there is a college life style/scene, and if so which ones are "party" colleges. Decide from there... the lecturers know which college the students belong to, which can be amusing when it's about the rugby, less so when they're despairing with the state the students have rocked up in...
-Parking is often limited at uni's, and even with a permit you're not guaranteed a park. Also, if the police are like here they regularly speed gun or RBT the roads around campus.
On the flip side, I went through the UK's clearing system and ended up in a rented room in a student house with 7 other students. It was great, and in fact there are 2 married couples that came out of that house - one lot have been married 11 years, the others 8 years, having met in September 1998.... I missed out the whole UK halls system, but the houses were good; my 2nd and 3rd year house was very Young Ones.
