I'm going to travel to Europe in 11 days. I'm going to UK, Austria, Czech Republic and Hungary, and here in Chile I can exchange Chilean pesos to sterling pounds, dollars and euros. I'm particularly interested in the Czech crown. Do they accept euros or dollars in Czech Republic? What do you recommend, euros or dollars? I'm going to use my credit cards (all contactless), but it's always necessary to carry some cash. I'll be in Czech Republic for two days and a half.
Thank you in advance.
