Starting April 1, the 70 hotels worldwide that are members of the Ritz-Carlton chain will offer at least one option for guests to volunteer during their hotel stay, reports USA Today.

Billed as “Give Back Getaways,” these volunteer opportunities will include conservation activities, preparing food for the needy, and other efforts.

Although the Ritz-Carlton is a luxury hotel, Sue Stephenson, the Ritz “social responsibility” chief who proposed the program and is overseeing it, believes that guests want opportunities to help others during heir leisure time. Most programs will last a half day and cost hotel guests $50 to $100 to cover transportation and a donation to the charity or group.

Some critics and nonprofit groups have expressed concern over guests viewing the volunteer work as a kind of “zoo experience,” but David Clemmons, founder of VolunTourism.org, a clearinghouse for volunteer vacations, who consulted with Ritz-Carlton on its new effort, said he was confident about the hotel chain’s approach. “I feel what they’ve created can stand up to the scrutiny and do good,” he said.
