Best things to do in Seville

The Cathedral iself is awesome, of course. That's why we are here. And in the event, the ticketing and entrance to it was just fine, as there was no queue to skip so 'skip-the-line' was unneceaasry'. Two hours later there was a HUGE queue, being carefully policed. See emails for my problem acessing tickets however. Your App is not easy and intuitive to use. The Audioguide was a complete washout, as it reqired a "Validation Code" to function and nowhere on the ticket nor your communications, app, or emails to me was there such a number. Obvious or not. Thus we had no other guidance during our visit than the heavily theological propaganda of the Catholic establishment.
