Focus on the Family and four other conservative Christian organizations are meeting today with Marriott International executives in Washington, D.C., to persuade them to remove in-room adult movies from their hotels.

"Pornography feeds prostitution and sexual abuse," Minnery said. "And it's especially dangerous in hotels because it can become addictive and create a sexualized climate that puts men, women and children at risk."

According to a survey by Citizens for Community Values, 75 percent of American hotel rooms and 90 percent of Marriott suites are wired with in-room adult movies.

"I think their campaign is a colossal intrusion on adults' free choice to view legal adult material," Cambria said. "It's the same as coming into your living room and turning off your channel. Hotels are the home away from home."
