Disney has long kept its cruise operation's finances close to the chest, never breaking out ship revenue in its standard earnings reports. But according to a new investigation by Fortune, the numbers have been quietly hiding in plain sight — buried inside filings from a shell company that doesn't carry the Disney name at all.

Those figures tell a striking story: Disney's cruise fleet pulled in roughly $3 billion during the company's most recent fiscal year, cementing the ships as a major and growing pillar of the broader Disney business.

The company apparently isn't done building on that success. Disney has plans to add five additional ships as part of a sweeping $60 billion expansion, a move that would significantly increase its capacity and competitive footprint in the cruise industry.

For Florida travelers, the news is particularly relevant — Disney Cruise Line operates heavily out of Port Canaveral and Port Everglades, making the Sunshine State the primary gateway for most of the fleet's sailings. More ships on the way means more departure options for Florida-based cruisers in the years ahead.

The financial details were first reported by Fortune.
