Thanks alot Michael_43 for your two replies. Very helpful & encouraging, and encouraging is good! Kulmbach's the one, looks like we're going to be in Altenkunstadt just down the Main valley, though still investigating other possibilities. As you say, lots to do in the area and as a member of the Campaign for Real Ale (CAMRA), one or two brewery visits may be on the agenda, as well as a trip to Bamberg, all strictly for research purposes of course!
Anyway, I look forward to meeting you at the show, armed with my Euros and boxes!
Cheers - Tony
