I doubt you'll find a place quiet enough to take a nap during the week. Whenever I'm there during the week it's pretty busy. It's easy to find a seat, but it's certainly not quiet. There is a large quiet room, but I've never been in it. Perhaps that would be a better spot to find a seat and take a nap.
