Not necessarily a good answer to your question...but I read something in my book about Masses when planning our trip that I thought would be interesting to pass along.
The unofficial guide had this to say:
On Sundays at the Polynesian Resort, mass for Catholics is celebrated at 8 and 10:15am. For a schedule of services and churches in the WDW area, inquire at your hotel's front desk.
Interestingly, we've been receiving mail from Roman Catholic readers about the Mary, Queen of the Universe Shrine, located across I-4 from WDW. Here's what a Roselle Park, NJ genteman confided after going to the Shrine for a regularly scheduled mass:
This "Church" held about 2,000 people, and we were encouraged to squeeze toward the end of the row like in the amusement parks to fit more people in. After the entrance hymn, a priest greeted the crowd, then proceeded to give a history of the "little church". Next, he began suggesting how donations would follow, the first of which donors usually put a check in teh basket! Well, after 15 minutes of a not-so-Catholic mass, I got up and left. As I made my way (out), I met a priest who greeted me warmly. I told him my opinion of the commercial I just sat through and he had no comment at all. He just looked down and walked away.
Several of our Unofficial Guide reserach team are Catholic, so we sent them to Mary Queen of the Universe to determine first hand if the reports we've been receiving from readers are representative. Here's there report:
You've got to be suspicious of any church that features its gift shop on its website, and the Shrine is no exception. If overt fundraising makes you uncomfortable, this is not the place for you. Upon entering the church, guests are handed a small pamphlet best described as a "rate card". Mine said I could get a roof tile with my name on it for only $50. For $900 I could get an entire pew seat. If you though indulgences were a thing of the past, the rate card notes that donors will receive "...remembrance in daily Mass; and all the spiritual benefits accorded the family of Mary, Queen of the Universe Shrine." Donation envelopes are stored like napkins in the pews. The Shrine purports to be a Catholic church, but is not affiliated with any diocese or parish.
