We often decide on a park while we're eating breakfast, or *gasp* get on the first bus that comes. We do park hop, I randomly do ADRs 180 days out based on the restaurants we really like. So it's not a big deal if we end up at a park and our dining reservation is somewhere else.
We'll do FP if it means we otherwise wouldn't get on a ride, sometimes, but single rider lines are great, too. We definitely don't care all that much about planning.
This is our touring plan too, especially the "first bus" approach. We draw fast passes, but probably give them away about 50% of the time as we change our minds about what we want to do before the scheduled return time. We make dinner reservations in advance, but frequently change our mind and cancel the day before the reservation. I guess our touring plan is just laid back, spontaneous.
