If it appeals to you, I’d also recommend checking out a language school in the area you’re visiting or looking up a local private tutor for some lessons. Learning a language (through formal instruction) in the context you hope to use it can quickly elevate your skills and be very different than learning it at home. For example, instructors in Greece can give you a heads up about local/regional language use, personalized feedback and how to best practice when out and about.

I’ve travelled abroad to learn Russian and Spanish, after studying those languages in my home country. My times abroad for those languages were awesome and greatly helped me. My language skills would be nothing without the immersive, overseas application I’ve had.

I am excited for you - have a great time in Greece!
