Camping in Poland - are there any laws?

I have just looked at flights again and i can fly from London to Gdansk for £37.77 so i may do it that way and spend a day and night in both Sopot/Hel area and Slupsk then head across to Poznan, Warsaw, Wroclaw then Krakow and fly home from Krakow - is this a bit ambitious for my first visit or do you think its do-able in 8 days, I will be walking most of the way?

I would say take the train and its easily do-able, they are quite cheap. I have heard that hitching is better in Poland than other Eu countries too.
I would only go to Warsawa if you have to, just because its a big city and will be more expensive.
If you are travelling by yourself you are bound to meet people on your travels ( best bit about travelling by yourself ). If you can learn a few words in Polish they will go a long way.

Are you in London ?
If not have a look at Centralwings who fly out of E'burgh or Wizz Air and Ryanair who fly out of Pestwick. They should have prices to match.

No i am in Dundee and found the following prices.

Centralwings (EDI to Gdansk) £77.99 - No return flights on 17th
Wizzair (PWK to Gdansk) £81.29 - No return flights on 17th
Ryanair (EDI to Gdansk) £81.02 - £54.19 return 17th

skyscanner.net (London to Gdansk) - flying with Ryanair £37.77

Will keep searching for flights though - Bussing between places might be the best idea when i am in Poland - thanks
