Their show at Gdynia, Poland

Hi there. I am sorry if this is the wrong place to ask, so delete if you must.

I am from Norway and are considering traveling to Poland to see their show on 5. July and was wondering if anyone else here either are Polish or European in general who also are going.

Is the festival close to the city centre/airport?

Anything else to note about the city? I am traveling alone and wanted to get the best possible place to sleep as well

Kindest regards.

Again, i'm sorry if this is the wrong place to ask. Had no other alternative at the moment.
