We scheduled our naps around what our schedule needed, so that most events can start right at the end of a nap. This gives you 3-4 hours for whatever you need to do. For example, I go see my sister every tuesday evening. Nobody questions when you say, "I can't make it by 5; it'll have to be 5:30." That's my 5 o'clock nap. My next nap is at 9; again, no one questions when you've been there for 3 hours, and it's 9 o'clock, if you say, "I've got to get home to bed." I usually don't get the 9 o'clock nap until 9:30 or 10:00, but that's not a big deal.

Last friday we were at a kind of marathon gaming party, starting at 7PM and going until about 2AM. At about 9:30 I was too tired to stay up, so I crawled into a corner behind the table where I wouldn't be in the way, and slept until 10. No big.

I would say that the ability to sleep in the car is critical. But if you get tired enough, you'll sleep.
