This one is going to be interesting...
I doubt that the Magic would move directly from NOLA to Europe, this would make for a fairly long trip, adding roughly 2 days to the typical itinerary... Now, you could potentially throw in a stop at
Castaway Cay and you have a solid 14+ night EBTA cruise with maybe one more stop... My take is that the Magic may be doing a repo cruise to maybe San Juan in April 2023 and spend a few weeks there, as it did in 2017 before heading to Miami or PC for the EBTA cruise.
Now, pre-pandemic, there was also a rumour that the Fantasy might be overtaking the Magic in Europe and
DCL had signed at the time a new contract with port of NYC significantly expanding the cruising season out of NYC.
Summer 2023 may shake some things up... or we end up with same old, same old...
