Since matrimony is a sacrament in the Catholic religion I believe the sacrament has to be performed in a Catholic Church I don’t see how the sacrament of marriage could be performed at Disney World!!!
I guess it depends on whether or not the chapel in DW has been sanctioned by the Catholic Church as suitable. Or they might’ve had a separate ceremony in a Catholic Church before or after their destination wedding.
Given the current “pope”, everything in the catholic church is up for interpretation.
