Will do. Thanks.

Honestly, I would order them and have them delivered. It will cost a little bit more than making them, but it will still be extremely low-cost compared to almost anything else you can do. With that little oven space and 50 guests, someone is going to have to be spending an awful lot of time in the kitchen putting pizzas in and out of the oven, checking to make sure they are done, slicing them and plating them and bringing them out to be served. I don't want to think of that being you, spending so much of your daughter's wedding reception in the kitchen in your nice dress messing with pizzas.

If you order the pizzas, they will arrive hot and sliced all at once, so no one will have to wait for the second or third batches, and neither you nor anyone else will have to spend all that time in the kitchen.

I'd order some salad, too.

Good thinking, gellchom. Thanks.
