Invitation wording question

[verovladamir]

I hate to ask yet another invitation wording question, but I feel like each of us has different needs. So here goes!

These are our invitations:

Here's my problem. Both of our parents are paying for the wedding (quite equally, I might add). The invitation company suggests that I write

Mr and Mrs Russell and Vivian Antrim
Request the honor of your presence
at the marriage of their daughter
Amelia Grace Antrim
to
Daniel Dwight Crouse
date time blah blah
something about a church
more stuff

It seems a little rude to do it that way, so I would like something like...

Mr and Mrs Russell and Vivian Antrim & Mr and Mrs Dwight and Jill Crouse
Request the honor of your presence
at the marriage of their children
Amelia Grace Antrim
and
Daniel Dwight Crouse
date time blah blah
something about a church
more stuff

but that will not all fit across the invitation unless I make the font size smaller.
What do you suggest?

In addition to that, how do I word the part about the reception? On this particular invitation, it simply puts "additional information." Would I say something like
Reception to follow at Potowatomi Casino
Address
at specific time

Also, do I just put the RSVP date on the RSVP cards, or does it have to be on the invitation too?

Thank you!
