They don't have any weekly services, but I think they still hold Catholic masses on Easter Sunday at the Contemporary convention center. At least I thought they did....
I think for weekly Catholic masses, they're referring people to Mary, Queen of the Universe. When I get home, I'll get a link to a site that has all different worship services in Orlando....
Sorry -- the services are no longer. Mary Queen of the Universe Shrine in LBV has Mass every weekend. They have their own website where you can check the mass schedule.
The Catholic masses and the Protestant service at the Poly were discontinued. There is an explanation as to why at the Mary, Queen of the Universe Shrine site. You'll also find their schedule. The church is not far from DD and is worth the trip to visit. It's sole purpose is to serve the tourists of Orlando -- it's not a regular parish.
