I have tried several search engines trying to find out where I can get tickets for the Christmas Eve service in the Vatican, not outside in the square? This has been to no avail and I would appreciate any and all help and information on this subject. Another question I have is...when standing in line waiting to enter the church is it basically a first come first serve seating arrangement deal? I have read that one should get there by nine o'clock to start lining up. One more question, if one were to arrive two or three hours before the service and needs to releave ones self, where does one go if everything is closed, do they have facilities there? Thank you for taking the time to answer my questions. ML
