hey there,
definitely you can, but why would you do that?
Unless you have piles of Ben Franklins it is much more convenient to bring your ATM/debit card and withdraw cash in PL (PLN) and EURO zone (EUR).
One important tip - NEVER change your money anywhere close to airports/train stations. Yeah, seems obvious but I did that month ago. ME STUPID.
let me know!

ps. sorry for Hawks not making it last weekend - my SEA friends are in mourning
