The March 31 cruise on the Legend seems to be the one most in jeopardy - but its possible to take that to NYC - One of the piers in Manhattan is open, NCL Getaway is in the other. Brooklyn is not open, as the MSC Meraviglia is in port. The same for the 4/7 cruise.
The 4/15 Transatlantic for the Legend could use Brooklyn, the Venezia is in dock at Pier 88 in Manhattan but the other port is open.
Now for the Pride - The first cruise out of Baltimore is scheduled for 4/21
MSC Is not scheduled to go out of Brooklyn as the Meraviglia is on a longer cruise on 4/21- so Brooklyn could be an option for that one, BUT she is in dock on the 28th, the return date so that would not be ideal either for the Pride. So if its going to be in NYC, it would likely be Pier 90 or 92 as the NCL Joy is in dock as well.
The same for the 4/28 sailing.
RCCL could use Cape Liberty on 4/4, 4/12 and 4/20
