I'm going ;-)

Svojsice is actually the name of the place the event is in too. It's here.

The nearest major city is Pardubice. Looks like there's a direct train from Budapest-Nyugati to Pardubice leaving at 14:10 and arriving at 20:12. There's also the option of Budapest-Keleti to Pardubice with a change in Bratislava leaving at 12:05 and arriving at 18:47.

From Pardubice it's about 20km to Svojsice and according to the Svojsice site there are buses every 30 minutes after 15:30 from the main bus station. Looks like the bus company is called Connex and tickets should be 30Kc (~1EUR). First bus back in the morning is at 06:00 and every hour from then. Ah, three years of learning Czech came in useful :-)

See you there then! :-)
