I need some help for a trip I am planning this fall.

I will be spending 10 days in Egypt and then arriving at 620AM into PRG on Monday Oct 10. My friend is coming to meet me in PRG late in evening in Thursday Oct 13. We will have until Monday afternoon Oct 17 to tour PRG.

Therefore, I am thinking when I arrive at PRG, I want to immediately travel to another city on 10/10 and plan to return on the evening of 10/13. It seems the most likely candidates are Berlin and Budapest, although, since I am flying, it can be to any city, really. I have already visited Vienna. Does anyone have any suggestions or preferences? In Germany, I have been to Munich, Heidelberg, and the Rhine Valley. I have never been to Hungry.

Finally, I am flying into Prague on a DL Skymiles award ticket via Czech Air. If I purchase another ticket on Czech Air on 10/10, can I check myself in all the way through? What is the earliest connection I could safely make?

Thanks for any and all advice!
