Hi, we are a brother and sister from the UK looking to spend a couple of weeks in Central Europe over the Easter holidays. Last summer we travelled from Croatia to Berlin via Budapest and Prague and we're getting itchy feet again!

What kind of places will be interesting in March/April time? It doesn't really matter what the weather's like as long as there's plenty to do, and it's cheap. We're both students and want to try and head off again in the summer (to Spain) so we really can't afford to spend a lot of money at all. I'm guessing it'll be too cold to camp in most of Europe?

Any ideas or itineraries or past experiences would be really helpful :)
