Looks like other than the one Fantasy 10-night sailing, the initial cruises that include Lighthouse Point are on the Magic. Interesting.
EDIT: "A seven-night inaugural cruise aboard the Disney Fantasy from Port Canaveral, Florida, on June 8 will allow you to be among the first to make a splash in the crystal-clear waters of this new destination at Lighthouse Point. This ultimate
Disney Cruise Line island destination itinerary will feature not one, but two stops at Lighthouse Point … and that’s not all! One day of sun-drenched serenity at
Castaway Cay also awaits your family on this once-in-a-lifetime sailing." $$$$$$$$
