I believe the season ends in October. It was necessary in July this year. My daughter's wore off and she ended up itchy all over everywhere at the end of our CC day. November though, I would say no.
As others have said, I heard the season is spring to early fall. It seems to be hit or miss during that time. I am planning on buying it for my cruise in July, but don't think you need it for Nov. Enjoy your cruise!
