Hello,
Quick statement about myself: if I wanted to go to a Latin Mass I would stay here in North County, at Saint Margaret with "Fr." Wallace. If I wanted a Latin Mass parish staffed by FSSP, I would go to "Fr." Gismondi (?) at Saint Anne's. But I don't want the Latin Mass. I want the Roman Catholic Faith of all time.
My options: since I live in North County, and don't want to burn rubber, money, gas, and oil on my car to get to the 9:00 am Mass with Fr Gerard at CMRI, I take the region's fine public transportation. Sprinter, Coaster, MTS bus #28. Sadly the earliest Coaster train that departs the Oceanside Transit Center is at 8:36am on Sunday morning. It takes ~60min to get to Old Town Train Depot. It's impossible to get to CMRI on time for Mass. My other option? SSPX at 4:00pm in the same Naval Training Center Church building in Point Loma.
Do you live in Mira Mesa? Assuming that you do, according to MapsDotGoogleDotCom, take bus #20, Green Line (the Santee trolley) red trolley to Old Town Train Depot, then MTS bus #28 to Roosevelt rd bus stop. You will walk 1 block to Church.
For Holy Days of obligation -- usually on weekdays -- take public transportation, which starts early at 4:00am, to CMRI's National City chapel owned by a good man by the name of Louie and his son Louie Jr.
For a regional day pass I pay $12. Round trip.
I did a Google Maps search for Mira Mesa to Old Town, and the earliest possible arrival was 9 and change. Your best bet is with the SSPX at 4:00pm. It's good and all but the only displeasing thing I have found is that after the Mass the congregation starts praying for Anti-pope Francis.
One last thing on sacraments: since you're coming from a strange and apostate religion that's foriegn to the Catholic mind, you must Confess your sin of participating in or attending a non-Catholic worship service to either the sspx or cmri. Before receiving Holy Communion you must let Father know about this so he he can give you First Communion and perhaps a conditional Baptism.
Good luck and welcome home.
