I need to order dollars / travellers cheques in the next week or so, and I was just trying to get a vague idea of what food / drinks etc might cost. I'm guessing it's going to be relatively cheap because of the exchange rate, but didn't know if everything ends up stupidly expensive cos prices get yoinked up for the convention... And were people eating and drinking in the hotel and charging to rooms, or going out and spending actual cash money, or bringing stuff in with them? (Hotels always confuse me as I'm usually a self-catering kind of girl, so the idea you get "free" drinks just for telling the barman your room number always seems really naughty

I know nobody's got a crystal ball for what's likely to happen this year, and it's not the end of the world if I get it wrong, as I can withdraw money over there and change it if I end up with too much - but if anyone can suggest a ballpark figure - or a "well, a burger cost X last year, and a beer cost Y, and a decent beer cost Z..." then it'd be much appreciated...
(I know there's stalls and stuff as well, but if I can just budget for the basics then I can work out if I can afford to get new boots beforehand!)
