Honestly, I had never heard of such a thing in my life, so even had I searched for it I wasn't sure I'd find what you are talking about. Ancient Faith is also the name of a website not affiliated with Antiochian Village, so I wanted to make sure we were talking about the same thing:
That said, yes, this doesn't sound too appealing, and indeed carries the fallacy of matching men and women via strict age groups. 30+ also makes it sound like it could be ages 50 and up there too. I hope everyone who goes finds love, but it looks like it would carry many of the problems inherent to any other form of dating. At least you know if she goes there, she is serious about her faith, so that is something.
Women under 30 wouldn't need such events, of course, so I feel like such singles events are for older women who no longer attract men as easily. Young women will always have suitors, within or without the Church, so therefore if a man wants a younger woman he needs to look elsewhere.
The options for gaining a young wife nowadays are tough, you either Church hop until you find a maiden, or you do the missionary dating thing and try to convert a pagan. Both ways very difficult. Pray to the Lord, do your best, and don't worry about the rest.
If was 45+ and single, I might consider the Singles Retreat, but otherwise I don't think so. If I ran the Antiochian Village, I'd make it so women under 30 get a free ride: plane ticket, room, board, and other expenses covered by the Church/Village.
