Hi Orbutt - just got mine and I was in the 90 Euro group. Expensive when you add the t-shirts (and I'm a sucker for them...) I've also just bought the flights today, so an expensive day, marathon-wise!
Karen - that's grim. I booked with airbnb.com this year, stayed in a really cool place in Keuzberg for £27/night. Check it out for a slightly more residential (and affordable) place where you're more likely to be able to sort your own food on the morning of the run... And wherever you book - remember to read the reviews and take earplugs just in case!
Gerry, I don't think you can, have you checked out the website?
