What you mentioned is definitely not the traditional form of Catholic party, though I guess that it is often common in those who are traditional Catholic in attendance but don't take it home with them...

You asked for an example of a wedding party.  So, I will give a few thoughts as to what I would prefer myself .  Yet I can not speak for everyone else...  :-)


Rather than lots of beer, hard liquors and such, there would be wine or champagne in small doses.

If there was dancing it would be more like line-dancing or square dancing rather than the modern hip-hop.

The music would be loud enough to hear but not blaring.  And the music would be uplifting, peaceful, cheerful and edifying rather than music with a lot of a beat and synthetics.  If possible having friends play live instrumental compositions would be ideal.

And rather than being a late night party, it would end by early-mid evening.


Once again...  These are just my thought.  And since many SSPX groups are very worldly, most of them would not agree with anything I have written.  

Anyhow...Hope it helps!  :-)
