Never used a touring plan. Didn't even know such a thing existed until maybe a year or two ago, and I've been going to Disney off and on for 30+ years, since I was a kid. We don't do table service, so dining reservations are not a factor in our Disney days. Prior to FP+ we did almost no planning. It was quite literally a matter of waking up and saying "where do we want to go today?" Now with FP+ and since we have switched to staying on-site, we do a little bit of planning. Basically our first park of the day tends to be determined by who has the morning EMH that day, our last park of the day tends to be determined by who has evening EMH/is open the latest that day. We usually ride standby in the mornings, with FP+ scheduled for early to mid afternoon, often in whichever park we hop to in the afternoon. We pretty much always have hoppers. That's the extent of our planning. We don't work by lands really, just ride whatever we happen upon that strikes our fancy at that moment, or whatever is showing a short wait online. We criss-cross the park a lot, but we are good with that. Efficiency is not really something I care too much about at Disney, short of maximizing the number of hours I can spend in a park each day. We went to
Disneyland for about a week earlier this year and loved being able to return to our no-planning methods. The old FP system really did allow for a lot more spontaneity and we really enjoyed a return to that.
