Take some time to celebrate on the Carnival Holiday, and sail from sunny Mobile, Alabama to the Yucatan Peninsula. The promenade is as bright as Broadway with a fiber-optics ceiling, colorful taxi-themed seating, and lighted theater marquees. For boot-tapping entertainment, head for Doc Holiday's, the western nightclub, while the frontier of virtual-reality arcade games is right next-door in Cyber City. Fuel your appetite with a day of sunning and swimming on the sports deck, then head toward a sea of dining options. From ice cream and pizza to lobster and Beef Wellington, there's cause for celebration for everyone.
