As noted in the FAQ section of the World Meeting of Families post below, the Holy Father will be coming to Spain for the event.
Zenit has a rundown of what the Holy Father will be doing in Spain. Apart from the standard ecclesial and secular protocol, here's the WMF portion of the pope's agenda:
[On Saturday July 8, t]the Bishop of Rome will then go in an open car to the testimonial meeting, which, beginning at 8 p.m., will gather hundreds of thousands of families at the Puente de Monteolivete in a context of prayer and testimonies. They will alternate with artistic-cultural presentations by artists...
Benedict XVI will repeat this itinerary the following day, Sunday, July 9, when he will return in an open car to Puente de Monteolivete, where he will preside over the 9:30 a.m. solemn closing Mass and deliver the homily.
During the Mass, some spouses who have celebrated their 50th wedding anniversary will renew their marriage vows.
