Saint Joseph Cathedral

I did not see any, but I would call the Cathedral and find out.

I'm not 100% sure. But I'm sitting in the cathedral right now and it sure feels like it is air condotioned. I hope that helps

Weekends

I would look on there website.

Yes indeed. Pretty big parking lot behind Cathedral..

There is a parking lot around the corner, kind of in the back of the church. It's a pay to park lot but free to church guests

The easiest place is under the Skyway. It does cost because it is municipal parking, but it is an easy walk. For mobility challenged people, there is very limited accessible parking on a first come first served basis.

Plenty of street parking specially if the wedding is during the weekend. Just make sure you look at the parking signs since some parking is designated to police and court personnel being downtown.
