(CNN) — Mickey Mouse is expanding on the high seas.
Disney Cruise Line will add two cruise ships to its four-ship fleet, the Walt Disney Co. announced Thursday.
Plans call for the ships to be about 135,000 gross tons each, a bit bigger than its two biggest ships, the Disney Dream and Disney Fantasy.
The new ships, which are expected to be completed in 2021 and 2023, will each include about 1,250 guest staterooms, the company said.
"We pride ourselves on the unforgettable vacation experiences we deliver to our guests each and every day, and the expansion of our Disney fleet will allow us to create even more magical memories for families at sea and in incredible cruise destinations around the world," Robert Iger, the Walt Disney Co.'s chairman and chief executive officer, said in a statement.
Disney released concept art for two new cruise ships.
"The announcement of Disney's upcoming ships is truly exciting news for both the line and the industry as a whole," said Colleen McDaniel, managing editor of CruiseCritic.com.
"Disney is always highly rated by Cruise Critic's members, and it's known for its dedication to service and over-the-top experiences," McDaniel said. "The line has a reputation for innovation, and we expect to that play out on the new ships. We're looking forward to seeing what's to come."
The company launched Disney Cruise Line in 1998 with Disney Magic and added Wonder in 1999, Dream in 2011 and Fantasy in 2012. Its home port is Port Canaveral, Florida, and Disney owns a private island, Castaway Cay, in the Bahamas for its passengers' use.
