But while Fleming said she was dissatisfied, she said she was "among very few people who had a problem with the experience." Dave Orton, who took part in the same activity during a different seminar in San Diego, said the "homeless activity" was eye-opening.
"I experienced what it was like to be a homeless person, people looking down on me because of my appearance," Orton told ABC News. "It does take you outside your comfort zone. It does put you in a place you're not used to. It's a place where you experience growth pretty rapidly."
Orton said it's thanks to Ray that he lives a life of "near constant gratitude" for what he has and that the price tag is more than worth it. Undeterred by the recent deaths, as of October, Orton planned to attend the Sedona event next year.
"The value doesn't even compare," he said. "To the people that say he's a fraud, I haven't actually thought of what I would say to them, it's so far out of what I see as reality. Have you tried growing yourself?"
For Fleming, the only thing that grew was her distrust of the self-improvement industry.
"I feel cured of self-help groups so that's something," Fleming said. "Maybe that's worth $6,000."
