I have always struggled with guessing PS times right, too. This trip we plan to take a different approach:
We've bought Connections vouchers - breakfast and Q&C. We've made breakfast ressies at a bunch of great buffets and character meals, later in the morning. We plan to get filled up on burnch, then pick up a snack or turkey leg later on, and use the Q&C vouchers for a later supper. Or for an early supper and snacks later on.
Every time we've done a big breakfast, it's messed up our plans for nice dinners later on. So this trip, we'll plan our eating around the breakfasts. And considering the Q&C is $11.50 and the Breakfast 17.50, that's $39 each per day prepaid for the majority of our food.
We generally don't like to jump up early and rush off to a park, but rather take our time. This should be an interesting experiment in strategy.
