we live in the chicago area as well and i would hardly hope or expect to find the world's best pizza in an orlando theme park.
i think this comes down to your expectations. it is a pre-made pizza, i would liken it to a "new york" style (i'm not looking for a fight here, i merely refer to the thickness and somewhat pliableness of the crust).
i used to lead the bandwagon against this pizza, but then something amazing happened, they taught the cm's how to properly cook these pizzas!
now we actually look forward to these as part of our trip. there's something fun and relaxing about a pizza at the pool when you need a little theme park break, and the kid's eat 'em and enjoy 'em (you could do alot worse satisfying their snack cravings).
i'd say give 'em a chance and make up your own mind. it's the same pizza throughout the parks/resorts. so if you don't like it at pinocchio's village haus (magic kingdom) or pizzafari (animal kingdom), you won't like it at pofq, and you'll be kind of limiting yourself on quick service food choices.
get a little crushed red pepper or parmesan cheese to sprinkle on it and don't approach it like a critic from the food network, as i said, it's now a part of the vacation that we actually plan for and look forward to every year.
