Nika said, in an interview with Maria, she isn't going home but spending the holiday with her Croatian friends in the city (not sure if that meant NYC or Hartford). Surprised she isn't spending it with Hana, but perhaps they have a longer break so she is able to get home.
As mentioned Aaliyah is going to Carolines and Lou, I believe said she will be with family in n New Jersey. So if two are going home that would leave Dorka and Ines. Hopefully their flights will not be canceled/delayed on either end.
