Thanks Rodndonna, that's a promising bit of news. It tells me that NCL planners feels that the turnaround time from airport to ship is doable. On paper anyways.
Graphicguy as always you are very insightful. I'm leaving from Chicago in February, on the only direct flight that day. The reasonable (unreasonable for me) option was to come in the day before. I guess I went through all the variables in my head before I booked this flight, just having buyers remorse.
