Hello everyone!
We are planning to visit Summer Punch Festival in june in Letnia Scena Progresji, because Bad Omens and other bands are not showing in Rock for people this year. We lack some information about it, because the website is almost only for ticket buy.
Do we understand right, that there is no campsite and we need to book some room?
How it is with paying there? Do we need to change cash, do they accept cards or do they have some festival chip for paying?
We usually walk a lot, is it okay to walk in night in that location?
Thank you everyone and see you in Warsaw, will be our first time there.
Ahoj!
