What I had written was John Heald should be the cruise director. I have been on the Triumph 3 times and will again the same cruise you are on. John should be back from England for our cruise. If he is the CD make sure you go to see "A Bedtime Story" it is hilarious. As for your question about the room sizes, I called Carnival and they said that those rooms are slightly larger. The reason is the layout, with the stairs right outside your door. Hope this helps.
That is good news about John Heald. I have heard very good things about him! I also asked Carnival about the room sizes and they did not come up with anything except to say that all 6B rooms are 220 sq ft.
Thanks for the information. Maybe we'll see each other on deck sipping a margarita!
