Victoria knows

They have a room phone. They certainly told people where they were so they could be reached esp for emergencies. They’ve shown Victoria using the room phone a few times. Timothy said “everyone at the club” - people know and are talking about it in North Carolina. Her brother certainly knows and she comes from her own money. I’m betting she’s made a few calls and found out and is already protecting her own money and family. Her reaction to Kate may have been worry that she may know and say something to the family hence why she was so standoffish. Timothy has been passed out and away from the room plus I doubt he’s checking the hotel room bill for calls.

Victoria will leave him and walk away fine. She’s not the pilled out clueless wife and it explains why she didn’t want to engage in conversation with Kate.
