4-Day Cruise and Formal?

[bananaman]

Ok, 8 of us are on the 4/20 Fantasy (ex-Sensation) to Freeport and Nassau....a question came up from DW and the other ladies last night as to when the formal night is. I thought it was the last night which is the day-at-sea (Sunday), but then someone else thought it was the second night (Friday). Does anyone out there know for sure.?

On 4 day cruises the Formal night is usually the second night.

Would it also be the second night on 5 day cruises? Thanks
