I should preface this by saying that I've only cooked pizzas twice, on back to back days.
With that out of the way, rolling/forming the doughs is what took the most time for me. Once that was out of the way, it only takes a minute or two to make a pie. Spread the sauce, add the cheese, layer on the toppings. I used 14 inch pizza screens on my cooks. Roll/spread/form the dough. Spray screens with Pam or alternative. Lay the doughs out on the screens and you are ready to go. When the cooker comes to temp, sauce, cheese and top your pizza right on the screen then slide the entire thing, screen and all onto the stone.
If you have other people there, this makes it easy to get them involved. You do the grunt work of forming the doughs. They can then sauce, cheese and top how they want.
