Carnival won't sail thru spill at nite
 

The one sailing back on May 22nd out of NOLA delayed departure until 9:00 so that they would reach the gulf during daylight hours. It had no affect on reaching the ports on schedule and worked well.

I just returned on the Triumph Saturday and Friday night when we reached the southwest pass right before we entered the Mississippi, there was hardly any oil visible at that time there.

My understanding is that the one sailing was the only one delayed and returning is not an issue.
