How does hotel fraud work?

These groups promote attractive deals with local accommodation providers, but once payment has been received, the company disappears and can no longer be contacted by phone or email. Once the attendee contacts the hotel directly about their room, they realize the hotel has no record of them or their stay. Not only is their money gone, they must then scramble to find last-minute accommodation, which is rarely closely-located to the venue.
