The Mitchells visit Pearl Harbor, especially important to a naval veteran like Mr. Mitchell. During the tour, the site nearly becomes the site of another war when Dennis drives a captain crazy with his antics. In the end, though, even Dennis is affected by the history of the area.
Now, the Mitchells find themselves on Kauai, the Garden Island. Despite fabulous vistas of canyons, waterfalls, and Hanalei Valley, Dennis only has eyes for an actual mountain of sugar. Much to the chagrin of their tour guide.
