Room Inspection

Shouldn't be too hard, laws in Greece arent probably that strict. And they are their parents after all, its not like some strangers going into the hotel rooms. They probably have some management supervision off camera anyways while the parents were searching the rooms...

I'd say the rooms are probably booked to the production company, not the kids themselves. The crew would then have as much right to access the room as the kids staying there. And much like the kids being able to bring (cough) guests (cough) back to the room, they could bring the parents to the room.
