On the high seas, Mickey Mouse is king — at least on Disney cruises. They ply the waters of the Caribbean, the Baltic Sea, the Mediterranean, the British Isles, Alaska, and Canada, sounding their signature "When You Wish Upon a Star" horn as they depart ports across North America and Europe. Both an internationally recognized and trusted brand, Disney offers travelers quality ships, routes, activities, service, accommodations, and food that regularly put it at the top of T+L's list of the world's best mega-ships.
