Nope, not a planner at all. We have a lot more fun by just seeing where the day takes us at Disneyland. We might say when we wake up "I want to do the ____ show today" so we coordinate around the time of the show.
I can't really stand highly structured activities and it wouldn't be a vacation to me if everything was planned. It would feel like a job and I would get too focused on trying to "tick" off each item that I had planned for the day and not have fun. I've seen people bring excel sheets into the park with color coding of what ride they will ride, when they will ride that ride, where they will have lunch, when they will have lunch, where they will have a snack, when they will have a snack, what part of the park they will focus on, when they will focus on that part of the park, when they will set up for the parade, what shop they will buy souvenirs from, etc. These lists go down to the minute... it's insane! That would drive me insane! We pretty much decide randomly in the park of what we are planning to do that day. No planning unless there is a parade or show that we want to see, then we will coordinate around that show time.
Planning for other trips is even less planning! lol
That's why I don't think I would want to even attempt WDW. It seems like EVERYTHING has to be planned there about 60+ days out and that is not fun at all.
