I know exactly where you’re coming from. I too didn’t want our guests to drive far from the church to the reception either, but we were/are on a budget so I did a lot of price checking. At one point, our reception was going to be in Walnut, so I was looking at catholic churches in that area. Some didn’t allow outside parishioners, and if they did it was a steep price; others didn’t return my calls. Prices vary widely; you’ll want to double check on the details if any of these sound good to you; it’s been a while and my notes are a little spotty.
St. Christopher, West Covina – $700
Holy Name of Mary, San Dimas – $800, but only $400 for Friday evening, includes church + priest, no music (the receptionist was really nice too; you’d be surprised how many are rude); looks pretty from website
San Gabriel Mission – $1000 for non-parishioners in the big church; something like $2000 in the chapel because it’s historic.
St. John Vianney, Hacienda Heights – $700, including priest, church, coordinator, music, alter servers
St. John the Baptist, Baldwin Park – $480, not including music
Sacred Heart Church, Pomona – $300 minus $100 refundable deposit
St. Madeline, Pomona – $500 minus $150 refundable deposit
St. Joseph, Pomona – $600
St. Frances of Rome, Azusa – $520, not including music
St. Dorothy, Glendora – $400, need letter from your pastor that it’s ok to marry outside of your church; can bring in your own priest
St. Philip Benini, Brea – $1200, yes, twelve hundred!
St. Lorenzo, Walnut – I think it was about $500 or $600 now, but once the new church opens in Sept. 2010, prices will go up to about $700-$800 (don’t have my notes for this church with me)
Hope this helps!
