Mary Queen of the Universe Shrine is great, there are several masses listed on the website. It is a tourist church, not an actual parish, it has beautiful music and a big nativity scene. It gets quite crowded, so go early. There are a few other churches nearby, but if you haven't seen the Shrine, you need to see it at least once! https://maryqueenoftheuniverse.org
We have used Corpus Christi in Celebration. We liked it because it is an actual parish. We did not like the touristy vibe of the other church. Disney does normally have Mass set up at the Contemporary. We did that a few years ago.
