It's a combination of things, and thanks for all the great replies. We love PPO breakfasts, something about walking through an empty park we all love. It's about those traditions we have come to love over many trips. It's about sitting at Crown and Thorn for the Epcot display. I wish I didn't need to book 6 months out, but it is what it is. The trickiest is when they shut MK for a party, and you have an ADR late in the park.
Thanks for all the good input. I will just keep watching!
