UPDATE:
Overall, the pizza party was a success! The concept of making multiple pizza pies at home, transporting them, and reheating was only partially successful. I brought 5 pies, but we actually only needed 3 pies due to all the other food that others brought. Only the pan pizza that I baked turned out well enough to suit my own personal pizza standards. The other 2 round pizza's I baked became too soggy after sitting too long sealed in the containers. I had to actually re-bake the one pie about 8 minutes in an attempt to get the bottom crust crisp again and then it was way over cooked and tough. The rim of the crust wasn't even edible.
If I was to do another "Pizza Party" in the future, I'd only plan to bake & transport 2 pies maximum. I'd bake the pan pizza first and the round pizza last. Goal being to serve the round pizza within 1 hour of fresh baked. I'd make a thicker crust on the round pizza just because a thicker crust would hold up longer before getting soggy. I'd also make sure there was a preheated baking stone baking available for the reheating. The baking stone is crucial! Any more than 2 pies does not seem practical due how the pies get soggy from sitting in a sealed container for an extended period of time. It was an interesting experiment.
