Thinking of travelling soon, opinions please!

My fiance and I are keen on travelling somewhere interesting in the near future (from the UK, within the next month or so) but we are both currently not earning and have a modest amount of money which we don't want to burn through too quickly, so this would have to be on the cheap, coaching and hostelling everywhere probably (drawing the line at hitchhiking!). We're both outdoorsy (my fiance more than me, he's a very keen cyclist while I'm more of a beginner/intermediate) but I also really enjoy the history and culture of a place. We're also VERY awkward eaters (I'm a vegan, my fiance is non-veggie and just plain fussy
) so this would also be a major consideration.
I guess my question is; where? We both like the idea of Central Europe (Prague etc) but it would be pretty darn cold this time of year, limiting the opportunities for outdoor stuff, or somewhere like Croatia, which looks amazing but might be awkward for us eating-wise...
Anyone got any opinions or advice on what we should do, or whether we should just forget it and stay at home?
