invite question

So I'm getting ready to send out the first round of invites to our out of country guests in a couple weeks, and I came across this dilemma.

I have several friends/cousins who are either married or in serious relationships, but who still live with their parents (yeah, don't even get me started on that one! ) So do I send 2 separate invitations to the house, one for the parents and one to my friends/cousins and their husband/SO? Or can I just send one since its going to the same house?

TIA!

i have a similar situation on my mom's side where my aunt and uncle house 2 of married cousins and their kids

i just plan on sending three separate invites to the house - one to my aunt and uncle, and one to each of my cousins and their families

HTH

ok, thanks!
