Travel / A Night or Day In GDANSK....how to spend the time?.. [9]

Merged: One Day in Gdansk

Dzień Dobry!

I am an Erasmus student who currently study at Warsaw. Me and my friends are planning to go to Gdansk this Wednesday (1st of April). I have a question about how I can go to Sopot to see the strangely built building in there. Also, I am wondering if one day in Gdansk will be enough? Besides, most probably the weather will not be so good. Are there any indoor activities that you can prefer?

Thanks for your helps in advance!
