Euronet

A Euronet ATM on Mykonos — handy in a pinch, but worth knowing its reputation before you tap your card. Euronet is widely flagged for pushing unfavorable dynamic currency conversion rates, so always decline their exchange rate and choose to be charged in euros instead. You'll likely pay a fee on top of whatever your own bank charges, so hitting up a local Greek bank ATM like Alpha Bank or Piraeus first is a smarter move.
