That is NOT a quick question!

In my experience, if you have some planners and some not - make it "seem" Laid back by not telling the non-planners all your plans! Talk ahead to find out if they have any rides they've heard about and must do, whether they want parades and fireworks, what kind of hours they think they,d like to keep. Then you make plans and just act as tour guide when you're there. My family's non-planners did NOT want to see my notes or heaven forbid a spreadsheet, but in the parks I'd just walk in the direction I had planned, or say "let's go ride Peter Pan!" As though it was a spontaneous idea. . . They followed along and weren't totally aware that it was planned out!
I feel like if you find out whether they've already heard about anything and know they want to do it, it definitely must be in your plans. I would think a first trip (or any trip!) has to include at least one parade and at least one fireworks/night show. Some rides, some shows, some character meets. Find out if there are any in your group who like more thrill rides and if they're tall enough; look up height-restricted rides and plan them into your plan or out of it as needed, then focus on the many family-friendly rides. Really, if you don't know what's out there, everything is fun and you won't know anything you missed! If you are willing to plan a bit and pick some of those rides, shows, and characters, all the better.
