If it were in Cambridge I'd save a ton on travel. I wonder if I can get free tickets if I goto JaGEx and ask.
The fact it's in London I find odd, especially as finding somewhere to stay in London is damn expensive over a weekend. Luckily I wouldn't have to, but still.
They're based in Cambridge, and the closest other city is London (which is well connected transport-wise, and most planes go there/close to there). Holding it in Cambridge would probably be cheaper for them, but it's not well connected transport-wise, and you'd be looking at the same price for hotels
Train is £50 for a weekend return, which sorta sucks, I may see if I can get a coach or something...
