I am considering (presuming award avaliability) going to Poland and a few neighboring countries in August. Right now, my plans look like this:
Krakow (if I feel brave enough, then a visit to Auschswitz from there) - train to Warsaw - plane to Gdansk .

Any comments on around how much time to spend in each city and the must sees and dos?
Also, how easy is it to get around using English and/or Russian?
