Ordered invites today but...

I'm not sure about the wording. Between my parents' names and FH's parents' names there is no 'and' . The woman said that bc it is a smaller invitation we have limited lines and therefore we cannot fit an 'and'. I'm not sure if I like this.

It will look like this:

Mr and Mrs XXX XXX
Mr and Mrs XXX XXX
request the honour of your presence
at the marriage of their children...

Am I nit picking??? Help!!!

I've seen it like that. We ended up doing 'Together with their parents...' but if we didn't ours would have been exactly the same. Except with 3 lines of parents.
