The trick at SWF is to get there early. First area of the park opens at 08:45, national anthem plays at 09:00am and you're off. Do Kraken, JTA, the dolphin show, Clyde and Seamore, and then eat lunch at 11am.
That's the key, most are still watching a show or just arriving. By the time you actually get your food and sit down, it's 11:30am. At noon, everyone realizes they're hungry and heads to the restaurants. You will already be eating.
It's kinda weird to do it, because, you're not really hungry, so you have to look at your watch, realize it's 11am, and head somewhere.
The name of the wood oven pizza place is called Voyagers. It's located near the sky tower. It's my favorite, and yes, it gets packed in the afternoon.
