It's also that Disney is bringing
Lighthouse Point online and needs to have regular traffic to this new destination. With
DCL's commitments to Nassau, it's unlikely that the Wish is going to make many stops at Lighthouse Point, so it appears that the Dream (out of Fort Lauderdale) and Fantasy are going to be running an awful lot of 4/5 night excursions to LP and
Castaway Cay. In summers, one of those two will be heading to Europe.
I think it's also Disney doing a market test to see what itineraries become more popular. Will Disney find that their private islands drive more customers than their newer ships?
It gets a little more interesting when the third new boat comes on board; they have an agreement for port 10 at Canaveral, allowing DCL the ability to board and disembark two ships at the same time, staff permitting.
