There are definitely things that can be done.
I had a case in Toronto where a 12-year-old was held in a room for a whole week. Suspicions were all around that particular room because men kept going into it. I asked the cleaning lady whether there was something going on there, and she said she didn't want to have anything to do with it. Something was going on.
Eventually that particular girl jumped out of a window. She wasn't really hurt and we got her to safety, but she wouldn't speak against her perpetrators. She did tell me that there were many kids taken to that hotel.
I think there has to be definitive direction to hoteliers about.... They should be advertising their hotels as clean hotels.
