When you live next to the largest Catholic Church is North America and one of the ten biggest churches in the world, you take the tour! You don't need to be Catholic, or even religious, to appreciate the beauty of this experience.
You actually do not need a guided tour to wander around, but the Basilica is so huge that it is very helpful. The tour guide, Dee, showed our group of ten on a wonderful hour tour at 11 AM on a Tuesday. If you can take a personal day or are visiting, I would try to visit on a weekday. Buses of people come on the weekends, and I was surprised how large my group was! People come from all over the world to visit here, as we had people from China and Puerto Rico come to see the church.
The art work is mostly mosaic throughout the church, and the crypt level is really cool. The inside of the upper level is huge with really interesting domes. Plenty of people describe it in-depth, but I think the most wow factor comes from the sheer size.
The gift shop is huge if you are Catholic, and the parking lot is huge if you want to bring your friends.
I still love the Monastery a little more because of the amazing gardens, but this is a fun visit once too!
