It depends - do you have young children, and what park are you going to try to do? We actually managed to get in and out of Crystal Palace (with a before-the-park-opened ADR) pretty fast, even though it was a character breakfast. They had a good buffet. Most of the parks have QS bakeries, for faster service. There are a number of good restaurants at the other resorts, but if you want some quality time at a park, eating at that park (or the restaurant at POR) is probably your best/fastest bet.
