Hostel Part 3 is purely a work of fiction. The story and characters are created for entertainment purposes and have no basis in reality. It's all part of the horror genre's imagination.
For me, it was the cultural exchange. Since people in the hostel were from various countries, we got to learn about different cultures. We had evenings where we would share traditional food from our home countries. I tasted some amazing dishes and learned so much about different traditions. It was like a mini - international community right there in the hostel.
Hostel isn't based on any true events. It's a product of the filmmaker's imagination and designed to entertain with its horror elements and plot twists.
