I have used NCL air before with no problems coming in the day of our cruise and flying out the day after disembarking with no issues at all. Flight times were great, I had plenty of time to get to the ship and getting back home atter disembarking was just as easy. The cost savings was great compared to booking air on my own.
This time, I would like to come in a day early to be able to see the city. Again, the savings are pretty substantial compared to booking the flight on my own.
My only concern is that I might not be coming in early enough to see the city (time zone is the same). I might be coming in at 5pm or later at night, which will only allow for a dinner close by the hotel and no touring time at all. Plan B is that I could stay after the cruise, this way i know I'll be in town all day after disembarking. Downfall to staying post cruise would be that flying in the day of the cruise will most likely have me on an early flight and I might need to stay at my local airport hotel, depending on the flight time. I have no way of knowing what the times would be now, but again, the savings are substantial.
Anyone ever used the one day deviation, precruise, and what times were you given? Did they have you flying in early or later in the day/evening? I know this is a general question, since your time might not be my time, but just trying to see if there is a pattern.
