After digesting the donut, which is the ideal self defense technique against a potentially dangerous donut (you just don’t know when they might attack), there still may be several hours left to kill in a hotel room - sometimes well over a day, depending on the tour. Sure, it would be easy enough to circumvent cabin fever by simply going out and seeing the town, catching a movie, trying out a new restaurant, or visiting the neighborhood zoo. But I’m more interested in addressing here what can actually be accomplished by NOT leaving your modern cave.
