Germany -- To avoid or no?

[medsoc]

First post... yikes!
As a short intro, I'm a 23 yo Canadian male thinking of traveling some of Europe for roughly two months this summer (tentatively June 22-August 22).

My questions is this:
What are people's opinions about traveling in Germany during the World Cup? Is it going to be so busy that it might be worth skipping this time around?


I will likely be flying into Paris, but don't really have a set itinerary of any kind. I'm kind of on a wing for the whole idea of the trip!
Places I would like to visit for sure are: Paris, Italy, Netherlands, Slovenia & Croatia.
Possibilities: Germany, an international student meeting in Serbia (Zlatibor August 1-7), after that... endless into Eastern Europe if I get that far.


I'm considering purchasing a Eurail select pass for Benelux, France, Italy, S&C, and I guess possibly Germany.. the reason for the question!

Cheers,

M
