Whether you were going to Europe or anywhere else, I strongly advise you to get film developed as you go. That way, if there were any problems you have an opportunity to re-shoot whilst on location. There's nothing worse than coming back from a trip only to discover there's been a cock-up and you've lost images.

I'm sure people here will advise you of decent labs in the different countries. The same goes for sources of film, Europe is not quite the desert some people may believe, in fact you can probably getting a wider range of films than you are used to.
