Whenever you get a chance to take a tour that includes "Skip the Line", take it. It saves an hour or two waiting in the hot sun. While you can't technically skip the line for the cathedral, the tour company arranges someone to stand in line for you so your wait is only about 10 minutes. After the talk outside and the tour through the cathedral (great talk, amazing cathedral), the tour took us through the baptismal (no waiting) and then the museum of the Duomo next door (skipping the line). The museum is quite spectacular in itself. Summary: great tour, glad we took it.

This tour was amazing!

Wonderful Duomo complex tour, guide was very informative.

This tour was disappointing for several reasons. We were told to be 15 minutes early to meet our guide, but she was a half hour late so we wandered through the crowds and worried until she finally showed up. Then the tour felt rushed because she was running late and had another tour to get to. Too, I was most interested in the dome itself and we weren't allowed close enough to see it. Had I known we would not be allowed to gaze into the dome I would not have purchased 4 tickets for the family. One positive was our guide. She was knowledgeable and apologetic about our experience.

Very good tour! The lines were long in August, but we did not have to wait. We got excellent information in the Duomo, Baptistry, and the Duomo museum. Although the guide's accent was a little difficult to understand, I recommend this tour.

Excellent tour - a little too crowded but worked through the crowds - fascinating details about all aspects of the Complex.

This was a good tour - BUT - we paid for skip the line - and the Duomo no longer has skip the lines - so we waited 35 minutes for the tour to start only to wait 35 more minutes for the lines. It moved but that part was a waste of and time. the guiding was good.

It was a great guided tour overall and worth it to skip the really long line to enter the Duomo.
The museum was closed at the time that we were supposed to enter so, our tour guide discussed the exterior.
Some time later, 30 minutes? the museum did open and we were able to finish the tour inside, however, our time inside was cut short.
We did have to wait in a long line to see the bell tower, and that was expected.
The entire complex is fabulous and worth spending much time there.

Misleading...The whole group was under the impression that we get to clime the dome..WRONG. The tickets to clime the dome is included BUT we had to make our own reservation to clime the dome, which we were never told and they were booked the day of our tour.

Not sure I would recommend this tour for the money. We couldn't get tickets to climb the duomo sold out- even though we paid for them on the only day we were there to see the complex. The tour company did get us tickets for the next day, but we were already going to be gone. Very dissapointing. Also, this is not a skip the line for either the group tour entrance or for climbing the bell tower. We waited in line for both.
