I guess my wife and I would fall into the commando style (me more than her). We actually make a binder with every day planned out. While we don't plan it to the minute we know where we want to be and what we want to do on each day. We list which parks have EMH, the regular hours of the parks the show times, ADRs etc. Then we just take the page of that day with us. I've told my wife we should make this binder a business somehow, that's how much detail and planning goes into it.
This is almost exactly what I did for the '07 trip, which my brother-in-law christened "Disney Boot Camp".

I created a color coded binder with the overall trip itinerary, a few pages on each park, plus my own notes and then distributed to each of the three families with us. I'm sure they promptly "forgot" where they had placed their copies, but no worries - I was on top of it!
For each day of the itinerary, I had a removable "cheat sheet" that I could fold up and take with me inside that day's park(s), which included:
Attraction Chart
* must-ride list organized by the basic chronological touring order
* whether FastPass is available
* average length of the ride itself (not including queue times, obviously)
* height requirements (no longer needed for this year's trip!)
* planned closures and refurbs
* performance times (live shows, parades)
Restaurant Chart
* meals served (breakfast/lunch/dinner)
* food style
* typical price range
* snack kiosk locations
* whether character dining is available
Character Greetings Chart
* character name(s) / group
* location / land
* times of day available
Play-by-play Guide
This is my down-to-the minute (ok, not really, but close) playbook on when to be where, factoring in when to get FP's and when I can expect to use them, when and where to go for ADRs (plus res#), etc.
All of this worked very well for the last trip. For some days, I included a "plan B" version of the play-by-play for events beyond my control (bus breakdown, rain, etc.). But more often I just referenced the charts on my cheat sheet for on-the-fly adjustments. And joking aside, the others used these cheat sheets for reference on the one occasion when the guys' and gals' itineraries diverged.
This year, we're going about 1/2 Commando and 1/2 free-style. Which means we do commando style from rope-drop through early afternoon and then switch up...
