OK I know someone who met his wife on a singles shabbaton where there were a range of Jews religiously speaking MO to Yeshivish, BT and FFB, etc. So much so that there was some activities that were not for everybody for instance they had Motzai Shabbos square dancing. He opted out and went to the hotel lobby and just stared at the fireplace there when suddenly a female voice asked him, “Are they really supposed to be doing that downstairs?” She meant the mixed dancing, anyway they started talking and it turned into his shidduch/beshert. – I thought(when I heard the story) wow all the ones who would say why not try it, it’s not disco you have to put in hishtadlus for your shidduch no it turned out the right hishtadlus was keeping shtark and true to your derech.
Hatzlacha to all singles may you find shidduchim hagonim b’karov.
