Thank you for the great tips, please keep them coming

I checked the LOT site and the WAW- Gdansk RT is around 260 PLN, so only $70 USD . How much is the train and how long does it take?

Looks like language won't be a problem since my Russian is at least as good if not better then my English (born in Russia).

Thank you for the tip on the driver, but I will probably stick to public transit. Cheaper, plus easier to get to know more about people that way.
