As long as the airfare doesn't unreasonably spike (and March is a superb time to get great deals to Germany among other Euro countries), this is becoming a greater possibility by the minute.
Lichtenfels is in Eastern Germany (more Southeast than anywhere else). And the closest major city appears to be Munich (not to mention....ahem...Prague, Czech Republic).
Closest airport would be Frankfurt or Munich. It is about 3 hours by train from Frankfurt or Munich to Lichtenfels. I just find Frankfurt to be a better choice than Munich when flying to Germany.
It is a good Fest. I was there in 2006 for one of the days. I was working the Primordial/Moonsorrow tour and that was one of the stops on the tour. It was very disorganized from a behind the scenes standpoint. Most of our crew ended up doing stuff for the Fest to make it run smoother. But the venue and everything else was real good. There were over 2000 people there in 2006. I was going to go this year but had to cancel at the last minute. Definitely thinking about going in 2008. So far I like the lineup for 2008. Ivo, the organizer, does a good job.
