I just noticed if the Kirkland-Bonnefoy kids did give Iggy and Francy a proper wedding, I bet they would also give them a chance to get a proper honeymoon since their first one was in a room Iggy was locked in and Francy could come and go from. 

I wonder where the two would want to go... probably someplace their kids, friends, and other family couldn't find them or spy on them.
