What others have said. I also heard they were having trouble filling the cruises (though hey - it got us a *GT rate for the one this past fall, which was amazing!) but I really hope that in 2021 they bring back that itinerary, as it's basically perfect for our family, and we had an amazing time.
But yeah - the dry dock pushed back when the Magic returns from Europe, which is cutting their time in NY down by A LOT.
