I'm working on my Seville itinerary today and though I cannot yet purchase my combo ticket for the Seville Cathedral/Bell Tower and another ticket for the Rooftop Tour, I see the times available. It looks as though the only time for the rooftop tour in English is at 1030am each day, and the tour lasts 1.5 hours.
That means I cannot enter the cathedral for the first slot of the day as I won't have enough time. I was hoping to beat the crowds. Fortunately the rooftop tour is limited to 25 persons, if I'm correct. I would be done with the rooftop tour at noon, but don't feel that's a wise time to visit the cathedral. I can opt for a late afternoon visit, they close at 6pm, or first thing the following morning. My Airbnb is just a 6 minute walk from there.
I'd be most appreciative for input from those who've done these visits/tours. Thanks in advance!
