I live in the small town of Kalush, and there is, of course, no Plaza. I can do little to help you.

Your girls need to go by train to Lviv, and from there to Poland. I heard that there are additional evacuation trains now.

Another option is to find housing with this service: https://prykhystok.in.ua/ Depending on where they find housing, go there.

So far, traveling by train is the safest way.

In any case, they need to go in the direction of Lviv. It is now the most popular emigration route, as it is the largest transport interchange near the Polish border.
