Part of Carnival Triumph's appeal lies in that there is something for everyone. From the adults' only Serenity Zone to the three main pools-one with a retractable glass roof- to the upper deck health club, this ship is brim full of options to indulge. There is a giant outdoor movie screen that shows first run films, and a quieter, more laid bacl lido pool at the back of the ship. Add in a huge casino and a whole range of quality shopping options, and that appeal become obvious.
