As far as the number of meals, I'd questimate that it was in the 225-250 range. Two of sisters and their husbands were only here for two days, my parents and my younger sisters were here for eight days, and my aunt and her granddaughters were here the longest at twelve days (although they ate breakfast and lunch at school, so that might drop the number even further).
It was definitely an eye opening experience, in more that one way. It convinced most members of my family to, at the very least, keep their pantry fully stocked and to have a supply of firewood. As for myself, I discovered several areas were my prep had fallen short; you wouldn't believe how many rolls of toilet paper fourteen people will go through in a day, and I didn't have any emergency construction material for when the hackberry tree took out a window (it also took out both decks, but those were of little concern at the time) and we had to block the hole with a tarp and a couple of blankets until I could get to Lowes for a sheet of OSB and some 2x4's.
I'm used to cooking for crowds, and the logistics always runs through my mind first. Most home cooks would freak about that number of meals for less than a week. You did good.
You did well all around, if everyone lived through it.
Pest about the window. I'm single, and if I lose a window... I need window cover more than I need that bookcase(table, &ct). I can get away with that. Don't try that at home if you are married. ;)
