People who travelled abroad to see them live, how much am I looking at moneywise?

Hi!

I've got a question that I know very much depends on where I'm from and what city I'm going to, so yes I'm sorry. But-

I didn't get a chance to get feuerzone tickets to Nijmegen, which is closest to where I live. Some friends and I were joking about going on a roadtrip to Coventry when the feuerzone tickets there weren't sold out yet, but one of them is moving soon(and therefor doesn't have the money) and the other isn't responding (which I'll take as a signal she's out) and she's also claustrophobic so I'd selfishly like to go without her (not because I don't want her to go, she just has a tendency to want to stick together while I want to get as close to the front as possible).

I'm now thinking about going by myself to the Lyon one, because that doesn't appear to have Feuerzone and the general admission tickets aren't sold out yet. But- well, I haven't got the funds to make it too expensive. The tickets are already the rest of my monthly budget and I'd have to get to Lyon and stay there as well. Now, living in the Netherlands the journey to Lyon won't be too incredibly expensive, but I'll have to arrive a day early to ensure I can go to the venue in time and I have to stick rather close to the venue to get back to the hostel/hotel/bed&breakfast/whatever, and I'm wondering if anyone who's traveled after Rammstein could give me an indication about how much they spent on it, if it isn't invading anyone's money business to ask as much.
