Ah, home at last. By the end of The Return of the King, the hobbits have returned to their home in the Shire. Despite the miseries that the hobbits have had to endure, and despite the fact that the Shire suffered, too, they go on to rebuild the Shire better, richer, and nobler than it was before the War of the Ring. Frodo decides that, "people [in the Shire] will remember the Great Danger and so love their beloved land all the more" (6.9.76). While it is horrible that the hobbits' home must be threatened, it is precisely that threat that makes it possible for them to appreciate the Shire in the way a true home deserves.
Aragorn's relationship to Minas Tirith is more symbolic than an ordinary person's link to his home because Minas Tirith represents not only Aragorn's dwelling place, but also his seat of power as King of Gondor. It's not about comforts; it's about rule.
Sam's constant memories of the Shire even as he and Frodo crawl up the side of Mount Doom tell us that he'll be able to fit right back into his old home life, once he's back from the quest. On the other hand, Frodo's inability to remember the Shire thanks to the tortures of the Ring foreshadows his own struggles with homecoming.
