An organization that tries to find housing in Philadelphia for out-of-town patients and their families is wringing hands ahead of Pope Francis' visit in September.

The Roman Catholic faithful are expected to fill all of the available lodging in the region during the pope's visit coinciding with the World Meeting of Families.

The nonprofit Hosts for Hospitals is looking to double its base of 50 host families so sick people far from home won't have to postpone such care while the pontiff is in Philadelphia.

Rosana Tovar is a case worker at Shriners Hospital for Children. She says that "many of these patients cannot choose their time to have treatments."
