Roadtrip involving keeping multiple pizzas fresh?

I am making a trip to NYC and there is this pizza place I LOVE!!! I plan on buying 10 Pizzas for the upcoming superbowl. I am Driving home the day before the superbowl. I live in Ohio. How would I go about keeping the pizzas fresh for that 9 hour drive??? Any ideas??? I will be driving home directly from picking up the hot pizzas
