"Tomorrow we are visiting Italy and France."
Translation:Jutro odwiedzamy Włochy i Francję.
Ah, thank you, I think I didn't encounter 'Włosi' so far.
I just checked the declension tables on Wiktionary and realized that only dative and instrumental case are the same. But it seems quite random... The locative of 'Włochy' is 'Włoszech' and the locative of 'Włosi' is 'Włochach'. That hurts :D
