We found out about the delay when we checked in at the cruise terminal. We were given an opportunity to wander around NOLA some more, but we were ready to explore the ship. Leaving New Orleans at night was impressive, made for some really good photo opportunities.
On the way back though, the oil smell was pretty strong, one lady remarked that it burned her eyes to stay out too long. I noticed the smell more than anything (many years ago JP-5 an I became friends).
