I'm visiting Krakow next month and not sure what's the best form to take money in. Before now I've only visited countries that use euro/dollars (so carried cash and retained leftover spending money) and I've also only travelled with family or a few friends.
However, there are 20 of us going as part of a hen do, so I'm expecting to be buying drinks in sizeable rounds.
My question for the experienced travellers is do I just bring cash, or do I use my credit card? I've heard people using monza cards but I have no experience with them so would appreciate any advice/guidance, so I avoid unnecessary charges etc.
Thanks!
