If you're willing to be the one to put the nuts and bolts of the touring plan together based on input from her, it might go a long way to getting her on board. My sister and many of my friends are not planners when it comes to vacation - they plan the basics and the rest is kept very loose. The idea of having a set "attraction itinerary" or the sheer depth of some of the crowd level information would drive them batty if they had to look at it. So they don't. They give me the things they know they want to do, and I do all the behind the scenes stuff. They don't want to see how the sausage is made, but they enjoy the benefits they reap from the end product.
To me, it's not about over planning or micro-managing - it's maximizing the efficiency of our fun. The fact is with a well done touring plan you can hit up everything you want in the parks, sometimes repeatedly, but all without feeling like you were just dragged all over creation at breakneck speed. Putting together a touring plan has allowed my travel parties to chill out in the parks because no one has to dither over where to go next or complain about having spent all day waiting in line unnecessarily. And in the event that you need to alter the plan day of, it's easy to remove or add items to the plan via the app and update it.
