Hi Aaron!,..How are your preparations for your trip to Poland? I hope everything is under control. I think that you must visit Warsaw. It is a beautiful city with many viewpoints. Your girlfriend told me that you want to visit the Palace of Culture and Science, but if I were you, I would choose the Copernicus Science Center with much more interesting attractions. There is, among other things, a planetarium where I literally felt like in space. Just watching it was magical and unforgettable. On vacation, apart from clothes, I usually take comfortable shoes and I advise you to do the same.,..If you have other questions just write.XYZ,..
