prague vs. cologne

[pinknic38]

okay I know I've posted about this little itenerary dilemma before but now we're at crunch time (30ish days!!) and I really need to make my decision because there are tickets to be bought and if I opt to do Prague instead, I won't need to get a rail pass because I'll only be taking the train to/from Munich and once in Frankfurt and it would be a waste of money.

So to summarize the issue, I go from Munich to Krakow and I spend like 4 days in Krakow then go to Prague then to Cologne and train it to Munich.

BUT I'm kind of iffy on Prague, and a part of me would rather come back from Krakow straight to Cologne and see Dusseldorf and Bonn too before I fly home to Frankfurt.

My main concern is Prague would probably be less expensive to see (since they don't use the Euro) and a recent money situation will be making my Euro trip VERY budget. I'm on the fence, I would like to see both equally and would have fun no matter where I went I think, but yeah that's the dilemma.

So whoever has been to Prague and then those areas in Germany, if you've got an opinion at all, it would be much appreciated!
