Punki - I sent you an e-mail based on your post in General TravelTalk before I read this one. Check your e-mail anyway, please.
As luck would have it, it looks as though I may be in Munich myself in April, but I'll be gone by the time you get there it looks like.

Planned dates, 11 - 14 April.
I'll
