For Gdansk the bill for landing there was EUR 25, which is quite modest in Europe for such an airport. AVGAS was EUR 2.78 per liter, or EUR 10.52 per gallon, which is on the low end of the European price spectrum.
10.52 EUR would be 11.48 USD with today's exchange rate.... I am so used to the prices here in the US, that it's sometimes good to be remembered, what I paid in the past. Even renting a plane is so much more expensive outside the US. We paid 120 Euro (130.91 USD) for a C152 which was dirt sheap for the Stuttgart area....
A very nice trip you did and a very nice write up. Thank you for sharing!!
