Just got back from our cruise on the Carnival Triumph and had a wonderful time!
The ship is older but well maintained. It is fairly easy to get around with a few spaces being a little more difficult to find. After a couple of days you get used to it.
The crew runs like a well oiled machine. Service is very efficient and the employees were usually cheerful, if not they were at least pleasant. I must say the cabin steward Johl was outstanding. He took very good care of us. If you are lucky you will get a cabin in his section.
This inside cabin is in a great location. It is located in between two floors of cabins so is quiet yet very close to the elevators and the action. It is also shares the same cabin steward as some of the most expensive cabins on the ship so the service is exceptional!
