Same problem for me. Arriving from Munich, the Bundesbahn now recommends travelling via Wien! Frankly, I have negotiated so hard with my wife to get this weekend off, but now it is about 10 hours travelling one way... hm. Actually, I don't know. Yet, for the case, Mirek, please provide more detailed information (starting time, address in Zlin...).
We will see :-)
@ Lars: in case you are travelling by car, think about doing the trip via Munich - we could share the fuel costs.
