As soon as I saw this thread title, I knew there would be mention of the Mary, Queen of the Universe Shrine. I don't know if there is anything on Disney property, but the Mary Shrine is very close. But beware, it is extremely popular and if you decide to go there I'd advise that you arrive early. The main road leading to the shrine is also the main road leading to the apartment complexes for Disney's college program interns. On Sundays and Wednesdays, it easily took an extra hour to get home because of the huge line of cars.
