- if you're flying into Charles de Gaul airport, bring 8 euros *in
coins* for the train ticket into town
Does the machine not accept Euro notes? Since that might be a problem for most of us I imagine!
(Supposedly ATMs and credit cards are the way to go, although most places don't like US credit cards because they lack chips.)
ATMs should accept US cards just fine, but you're right, credit card machines and ticket machines tend not to be fond of chipless cards.
Cheers,
