Ah, vacation. Is there any sweeter word? It conjures the smell of salt air, the warmth of summer's rays, the sight of water so sparkling blue it's blinding. While it's true that you can bathe all five of your senses in such pleasures at a vacation resort on land, there is simply no better way to enjoy changing views and multiple destinations than a vacation at sea. You can select from dozens of ships based in hundreds of ports around the world. Welcome to the wide, wide world of cruising.
