Travel / Gdansk - where to go and what's cool to see? [25]

Merged: What to do in or around Gdansk

Hello. My name is Martin. I am travelling to Poland with my family this summer (july or august). We have got plan to go to Gdansk for about 3-4 days. But we actually don't know what to do here. We would like to go around city in Gdansk, than we want to see Gdansk zoo. Can I ask you for some good attractions (what to do here or around the city). I've seen Aquapark in Sopot, than JumpCity in Gdynia. Have you got some more ideas for me? It would be great if you would help me! Thanks
