It makes me a little sad to think that not everyone got to go when it wasn't scheduled like a busy work day. And 10 years ago and earlier, it wasn't. You could treat it like a normal vacation - schedule your travel, book your room, and then just show up and have fun. Decide when you got out of bed what park you felt like going to. Eat what you wanted when you wanted. Our honeymoon trip in '99 is still probably my favorite, because of the utter freedom we had to just Be At Disney. There was a time you could go to Disney without a watch and still eat steak in Canada on a whim.
About 10 years ago it started changing. Now if you want anything other than counter service and potentially long waits for things, you schedule, plan, figure out which park is open which hours, check the crowd websites, rearrange your schedule, decide 6+ months out where you are going to go on which day, mark your calendar with the 180 day dining reservation dates, search and book tables, schedule some more, realize you have to change something, frantically try to find a new reservation time, etc. Now they want me to carry my cell (which I prefer to leave locked in the safe, because... I'm on vacation!) to keep up with their app too. I was looking at our Christmas trip reservations yesterday, and due to the addition of FP+ on top of ADRs we have as many "appointments" on the calendar for each day at Walt Disney World as I have in the average day at work. This amused me. Heh.

(At least I don't have to come to my "meetings" at Disney prepared with PPTs.

)
Of course we still go (a bit less often, sadly), and of course we still have fun because DISNEY, but it is now hyper-scheduled fun on super-scripted rails.

Keep your arms and legs inside the ride at all times! And don't forget your watch.
