Amber,
Most guidebook itineraries have a one-or-the-other approach. You have kids, and the world is all kiddie rides. Or there are no kids, and you are in rollercoaster heaven. Nothing in between. That is why I prefer to create little wallet-sized cards that have a checklist of all the attractions marked as either "
Ride", "
Avoid", or "
Maybe". There is one guidebook that has cards like that, or you can make your own.
For me it is great to have all my notes in my pocket on those cards, and I can leave the guidebook back at the hotel. Then when I get to the park I simply go from land to land, riding the ones I want, skipping the ones I don't, and hitting those Maybes if we still have time left.
As for a plan of where to go first, I follow one simple rule;
Go to the lands that I want to visit the most right away.
I am on vacation, not a work trip. Even if I have to deal with larger crowds I would rather be in Adventureland enjoying myself, than in another land wishing I were there.
Have a magical vacation!
