The Carnival HUB is a must have on most cruises as the only way to turn your fantasy into reality, and it has all new features. Its easy-to-use layout consolidates major ship information into one convenient place, so there are no cumbersome paper schedules or countless trips to Guest Services. The app can be accesses through the ship's Wi-Fi, making it available for any passenger who is onboard without having to purchase an internet plan.

One of the best features is the ability to manage events and services in real time. Users can also check daily schedules of hundreds of events, tick off favorites and set reminders to not miss anything. The app also offers helpful day-of travel information such as dining menus, hours of operations for venues, weather details and port arrival times. And for good measure, it offers food and beverage ordering delivered just about anywhere on the ship as well as virtual queuing for certain offerings to minimize idle time in line.
There is also the fact you can communicate and manage your account from within CTDP that's pretty big. For a low flat fee, guests can access the chat function to keep in contact with family as they move throughout the ship. The app also provides real-time updates of your Sail & Sign shipboard account balance, so you can keep an eye on spending without having to visit a kiosk. Interactive deck plans, the ability to book shore excursions or spa treatments and more also make it a comprehensive cruise companion.
Bringing all the components of a traveler's journey together in one place, guests can book spa treatments, make specialty dining and shore excursion reservations, choose internet packages as well as access information on everything from custom photo packages to detailed itinerary information.
