It isn't that people don't understand, or that math is hard, but that it is a different policy than the other Disney parks. People who haven't previously visited DLP pose the question because they aren't sure if there is another way to make their reservations. Please don't feel obligated to answer questions if you find them repetitive or annoying.
@GenGen22 because of the extra park day, I cut one day off of my DLP hotel stay. The DLP hotels hold bags so we will spend our last day in the parks, pick up our bags in the evening, and stay in a hotel closer to the airport.
