I was reading earlier something about a halloween party on board. Is that true? Do I have to pack a costume?

We were on the Triumph last year at Halloween. You can bring a costume if you want. There were a lot of people in "Togas" running around the deck,but I don't remember seeing a lot of costumes. There was a costume party on the Lido deck, but we chose not to go to it.

That sounds like fun. 

There will be  halloween festivities

to liven  everything up .

Nothing is  mandatory  ...so you dont  have to bring a  costume

They will have Formal Pictures  with Halloween Backgrounds  for  you to pose  with on the  last FORMAL night .  I got a  really nice  picture doing that .    But  I didnt  wear  a  costume myself

I did see lots of  costumes, especially the  ship's  crew  members  were  all dressed  up . 

It  was  a  good time
