I have a week off next week, and wanna go somewhere outta London, but not too far away.

My options so far are:

Dublin
Edinburgh or Glasgow
Dorset
Isle of Wight?!

I've never been to Scotland OR Ireland, and don't wanna go off to Spain or somewhere on a package deal (went to Turkey last September and got bored pretty quick)... so, suggestions?

I'm looking at maybe three days away, so a small break rather than a proper holiday.
