The attached video is from a ABC affiliate investigative report on the Sundance office in Indianapolis, Indiana. (They call themselves Smartravel, but it's the same company as Sundance, with the exact same sales tactics, steps and Travel Advantage Network Product.) The owner, David Wise, who is interviewed at the end of the news clip is direct business partners with the owner of Sundance Vacations, and they're all connected to Travel Advantage Network.
The video speaks for itself, as the ABC 6 team went undercover and actually videotaped what it's like going to a Sundance sales presentation. Definitely worth a watch.
