Your spare bedroom, organizers of the World Meeting of Families 2015 hope.
The archdiocese has partnered with Homestay.com to match up visitors and local families. If you would like to provide a bed to a pilgrim, you must register for free and complete a profile on the Homestay booking platform.
Visitors attending the event will soon be able to access the Homestay database to search for a host family that would be a good match for their accommodation needs. Visitors will have the opportunity early this year to correspond with a host family before committing to staying in their home.
Thousands and thousands of beds are needed, planners say.
The archdiocese has posted a FAQ and a video with more information.
