fly from Gdansk
I think you mean fly TO Gdansk , not from...? But in any case your best bet for such a journey is either pogo stick , or space hopper , if you can find one in good condition.....?
Seriously tho , Both places ( Gdansk , and Olsztyn ) are not so far from me , and i would be quite happy to pick you up at the airport , and take you to Olsztyn for the price of a bit of diesal fuel...
Normally i would be happy to do it for free , but my finances will not be in so good shape after my trip to UK to get another car , as mine is in need of replacement...
Of course it depends on when you want to go there , i collect the new car in about two weeks , and i am up to my neck in being part of a film at the end of may to begining of june , does this fit in with your plans...?
I do have the Harley of course , but it might not be your cup of tea , and it has absolutly no luggage space..!
The new car is a Jeep cherokee , so plenty of room for tons of luggage , quite comfortable , and being a diesal quite economic on fuel....
I can,t advise on travel by bus or train in Poland , as during the five years here i have never used them , my first experiance will be during the trip to Gdansk to get a flight to Liverpool to collect the car....Let me know what you think....?
