Try some of the religious houses for Mass, like the Dominican House of Studies across the street, or St Anselm’s about a mile from campus.
I got a Master’s at CUA and used to love going to the shrine to pray in different chapels. Each gives perspective on some part of American Catholicism, usually an ethnic group. It was just nice to get a feel for the small groups within the enormous Church.
Do not overload yourself with going to too many places. The aim is to get an experience of prayer so some time getting familiar is better than just rushing to meet goals.
