The Carnival Freedom and Carnival Valor are at sea in the middle of their voyages. The ships will stop in New Orleans on Saturday to replenish fuel, water and food supplies. Travelers will be able to disembark or wait out the journey back to Galveston, Carnival spokeswoman Jennifer De La Cruz told the Miami Herald.

Carnival Breeze and Royal Caribbean’s Liberty of the Seas -- both in Cozumel, Mexico, -- were scheduled to arrive Sunday in Galveston, the Herald reported.

The four vessels have a combined capacity of about 15,000 cruisers.
