Krakow

Hi! I’m new to this board but just read an older thread about this basic question and was hoping to get some additional information. I’ll be traveling through Budapest, Krakow and Prague this summer (in that order) and am trying to get a feel for how expensive rail travel between the cities will end up being. This would be in late May 09. We would train out of Budapest on 5/27 (to Krakow) and then out of Krakow (to Prague) on 5/30. If anyone could shed some light on this for me, I’d really appreciate it. Thanks in advance for helping!
