need help with wording...

Hi Girls,

Sorry I haven't been on in a while, I started a new position at my job and I'm super busy. I am missing everyone!!

I need some help with some wording FH and I want to take all our family pictures before the ceremony so we're putting an insert in the invitations for immediately family that they are to be there an hour before the ceremony starts. I'm having trouble wording it. Has anyone done this? Any suggestions?

TIA!
