Remarkably (perhaps), it is completely possible (and perhaps most common) for folks to vacation at WDW doing a very small amount of advance planning, of the sort we discuss here, and carrying nothing with them to their vacation other than, perhaps, one lightly-read guide book. The remarkable thing I've noticed is that a substantial number of folks who do so little planning actually have an excellent time and cannot wait to go back. I'll hazard a guess that the percentage of satisfied guests is perhaps as high as with regard to those who do plan ahead. I don't think that they actually get more out of their vacation than active planners do, but I believe, perhaps, a greater percentage of their expectations are fully met.
