Are you visiting any other parts of Europe (Sweden!) at the same?
We wish!! Sweden unfortunately requires way more time than we have We're going to fly in and out of Munich though, so we'll be spending several days there after Metalfest. I've been to Munich but its been 10 years since I was there, so it'll basically all be new again I would like to try to make it to Prague, but I just don't think we'll have enough time. If anyone's been to Munich recently, I'll gladly take any good advice you have!
Memnoch, are you taking your RV to Croatia, or are you staying somewhere? I still have so many details to figure out
