Yes, there was a Mass at CR at the convention center in 2004 Christmas Day. We went to it and then back to the Swan because it was very rainy and cold.
Thanks Patsfan7 for clearing up the taxi downtown disney info. I had posted that not realizing people would think I walked. The taxi drivers get charged a rate just to enter disney property. Anytime going off site, it is cheaper to first take the bus to DTD and then get a cab. You save on all most any off site destination. You save money and it costs time.
