I sailed on the Triumph this past December (7 days Western Caribbean). It's a lovely ship and we really enjoyed our trip, despite bad weather. Our group of six ranged in age from 18 to 55 and everyone had a great time. We had one inside cabin and I took a guarantee and was upgraded to an oceanview.
I felt that the dining room food was very good, enjoyed the New York Deli and Carnival's 24 hour pizza is excellent. Their casino is not large, but they have some great clubs and a super sports bar.
A good time was had by all -- if you have any other questions, just let me know. We got excellent rates for this trip and would sail her again.
