Invitations.

Here's the deal.  My fiance's father is paying for the rehearsal dinner, and my father and step-father are contributing to the rest.

The F and I are still working out our budget for the smaller things, but between the two of my dads, their contributions will pay for somewhere between 50 to 80% of our total wedding costs, excluding the honeymoon, which we'll pay for ourselves.

I'm having a hard time wondering how to word the invitations and would love some suggestions.  Basically the way I'm wording it is this:

Prospective Bride and Prospective Groom, along with their [fill in the blank], request the pleasure of your company at their marriage.  It'll be more exciting than that, but that's the gist of it.

Is it appropriate to say "together with their parents" when his father is paying for the rehearsal dinner only?  I'm assuming it's OK to say Bride and Groom (together with whomever) if we're all sharing in the costs.  But how do I handle the "their"?  Is the rehearsal dinner considered part of the wedding, and therefore a "together with their parents" is appropriate?

Many thanks!

Thank you.  I had a feeling that was the most appropriate way to handle this.  The last thing we want to do is cause hurt feelings...

Kaani,

Thanks for your response.  I like your solution very much.  Let me throw another monkey wrench into the plan:  how would you word the "Mrs. and Mr. Stepfather" if my mother is deceased?  The complexity never ends...

Vintage,

It's amazing to me how non-traditional the world is right now with relationships, and how, for some reason, we're sticking with tradition for things like wedding invitations.  Thanks for your response.
