The article essentially says that what we experience last is the most memorable, so by keeping trips compact, we spend more time experiencing the intensity of those last moments.

In a recent paper in Psychological Science, psychology researchers Ed O’Brien and Phoebe Ellsworth had University of Michigan students taste five types of chocolates—milk, dark, crème, caramel, and almond—varying the order in which they were eaten. Some students ate the last one knowing it was the last; others were not given that info and were left to assume it was just another in the series. When later asked to pick which one was their favorite, two-thirds chose the last one when they knew it was the finale when they ate it; only a fifth did so when they hadn’t known it was the last.
