I hope I'm posting this in the right spot

I'm ABC.
We're planning very tiny destination wedding of just our families bc F's famliy is in Europe and mine in the US. It will probably be the only time our families will ever meet. Problem is, his family=no english, my family=no french. Should we try to find an officiate to speak both french & english? I'd like to make it as comfy as possible for everyone. Any ideas for breaking the ice?
Also, F's parents are divorced and there is a gf (reason4the divorce). F detests the gf but wants his dad there (dad always w gf)... gulp....
Does anyone have any suggestions or have been in similar situations for their weddings?
