I agree with doing what works for your family. If you are generally structured, then have a structure, if not, then don't! Or you can change it up and just have a plan and be flexible.
I have a general plan when we go, which takes into consideration park hours, and our ADR's. But there have been many times, due to the weather forecast changing, we've had to switch things when we arrived. For example, extended rain on a water park day, etc. Don't panic if that happens!
Also, traveling with kids can change things. It is best to have the child guide your next steps. My son when he was roughly 2, needed more breaks than I had anticipated, and then once my nephew got sick when he was 2 because he was overheated and tired.
I've learned that mapping a plan is good, and that relaxing and food are the two biggest needs for our family. We will never see everything in one trip, and that is ok! It just gives me more reason to go back!
