A question for any experienced cruisers that have cruised in October, I was wondering about the Halloween party that the Carnival ships have that month. The Vista has the Sail Away deck party, 80's Rock-N-Glo party, and the Hot White Night. Do you know if the Halloween party is in addition to these or does it happen to replace one of the parties. I know schedules are not written in stone and can change. I really want to go all out but I hope to avoid spending money and packing things that I may not even use.
