If you've read the previous three sections, you will notice two things:
Indeed, dear reader. Indeed.
So, how do you choose?
First and formost, do what works best for you and your travel party. That's what free will is for.
But I do believe that there is an ideal guest behavior that can be achieved. And by behavior I don't mean that you smile all the time and have toddlers that never melt down in the parks. What I mean is that there is sa set of choices that you can make that Disney wants you to make.
I know that sounds creepy, but after fifteen years of working in the Front of House for one of the country's largest theater festivals, the last eight of which I was the Director of Audience and Volunteer Services, I understand seeing a large enterprise (such as Walt Disney World) as a machine, and individuals are the machine parts that keep it running - or break it. An individual's behavior, however, is ultimately unpredictable. Or, as I like to say, human behavior becomes a variable. If you make the choices that work best for the machine, the entire experience will be much, much smoother for both you and the parks themselves.
Completely unscientific, unofficial, and my best guess
Pretty simple, huh? The best companies who deal with the public make it pretty straight forward. Remember: Walt Disney World has many, many choices, options, and personalization options for your vacation. While this is what I think Disney would like every guest to emulate, you do you.
