That sounds way too familiar < G > . My wife isn't as bad, but that was a typical scenario when my kids were younger. Today, our two kids are grown up, living in their own homes but I know their sleeping-in habits haven't changed much.
When they join us, my daughter and her S/O actually enjoy sleeping in their private V-berth while we shove off at 6:00. They usually come out in a couple hours and treat my wife and I to some exotic, mid-morning brunch - they both have professional cooking experience . . . one of the perks of being the Captain & First Mate.
