@cornelius_blackfoot most of the time avoid your uk cards as banks will sting you, if you don't want to walk about with a huge wad of cash then get a travel card(credit or prepaid), caxtonfx and fairfx have been good for us in euros(one visa and the other mastercard so never end up somewhere without a working card, maybe OTT for one trip but it made sense to mix it up when gf went to get a card too).
