I enjoy the planning and the anticipation of executing the plan, as well.
My first visit to WDW as an adult was a disaster because we didn't plan. We now have gone to Disney 2 more times with a plan, and we love it.
I am really an armchair traveler in that I can waste hours dreaming about a trip...actual ones and virtual ones. For me, the planning is part of the fun. I plan what we'll do every day...ie. which park? which first few rides? our dining plans? our 'parkless' rest days? etc. Then, once we are there, we pretty much follow that guideline, but we aren't unhappily married to it, and we will change course midstream if we feel like it.
I love Disney, but I would never want to go more than once a year...or 50 times in my lifetime. To me, there are so many other places I want to see. So when we do go, I try to see as much as possible. The 'commando-ness' of our approach both depends on the park...and the time of day.
Epcot is our favorite park, so after we knock off a few 'must-do's', we lollygag and wander and drift. Same with AK.
At MK, we are much more into the attractions than the characters,etc., so we are more attraction oriented and coordinated.
It works for us.
