Questions to ask before this sort of presentation?

Hey guys, I'm planning my presentation on Cracow, Poland and I was wondering what sort of questions should be asked towards the audience for a show of hands.

I was thinking something along the lines of who has traveled to eastern europe? and has anybody thought on travelling to poland? (if not many, ill say something along the lines, well this is why i think you should travel there etc. and start my presentation.

any ideas?

That is fairly specific, why a presentation on Cracow, Poland?
