Here it is 3 years on and I'm still thinking about this trip. In fact, I have it booked for 2017. (Thank you Austrian Airlines for opening up generous award inventory on your nonstop LAX-VIE that begins April 2017.) We will fly into Kosice, spend 2 nights there, then go to Bratislava for 1 night and on to Vienna. Has anything changed logistically? Are there better/faster train connections between Kosice and Bratislava? Should we buy tickets in advance rather than waiting til we are in Kosice?
