Advice?

Not a what-I-ate-today post, but some questions about what-I’ll-eat-later.

Next week I’ll be going to Germany for a few days with the band I’m in, going along with another band we’re friendly with. We’ll be playing several tattoos in the Berlin-region (I think. Berlin isn’t actually on the list of places we’ll visit, but everyone keeps going on about the Berlin trip) and with the playing and the practicing, I kind of doubt I’ll be able to check out the local supermarkets for my food the way I do when we visit the UK for a few days.
Shame, really. I always love that bit about going elsewhere.

We’ll be staying in hotels, and some arrangements regarding food has been made as well. However, I have no way of knowing if there’s anything vegan available.

So. Questions.

How likely am I to come across people who speak enough English to grasp the basics of veganism? I can explain it in English well enough, but my German is pretty appalling. More like Dutch with a vaguely German accent than actual German, so I’m hardly a confident speaker. Dutch people are generally under the impression Germans are only marginally better than the French at speaking any foreign language, though the (non-tourist) Germans I met were always pretty good at it. They were all around my age, though. I kind of suspect people involved with the organisation of something like a tattoo might be a little older.

How easy is it to get basic vegan foods? While I was at the
Animal Rights Gathering 2007 (or, as some politicians here referred to it, a training camp for eco-terrorists. vboj) a British guy was very surprised at being able to find various kinds of Alpro Soya in the fairly small local supermarket, so I might be a little spoiled.
I’ve found vegan.de which seems to have decent general information, and Meta Filter made mention of ubiquitous falafel stands, which would be excellent, but I don’t know if the places we’ll be visiting are all that big. I’ll probably not have much free time, so I can’t skip all around town, leisurely looking for yummy stuff.

Does anyone have some practical advice on foods to bring along? I already have a few things to take along. Mostly snacks like ontbijtkoek, crackers, and studentenhaver (nut and raisin mix), but also two tins of Turkish beans&veg that could make a half-decent meal. It’s not much, but I’d like to take at least something. I could still go to the market and get me some more dried fruit there, but a lot of that is quite sweet and probably not too filling.

I’m not particularly worried about starving, but I’d like to feel at least a little prepared. And while I won’t starve to death, I would enjoy this long and hectic weekend a hell of a lot more if I’d have some food occasionally. It’d be great if it tasted okay. Ish. I’d settle for vegan and okay-ish. I’m easy.
