Just a quick grammar Nazi point, it should be "a University", not "an University"...

Sorry this one annoys me, just because a word or acronym begin with a vowel does not mean you should use "an".

It's full of hoards of stupid American tourists :)

There's more to "Eng-er-land" than London. It's a piss-filled city and really not that nice, which is like most capital cities around the world.

I personally wouldn't take a laptop, unless you like having a ball and chain around your neck.

Take some warm clothes, and the minimum amount you need, use London as a launch pad to the rest of the UK and Europe
