Cruise ship Ovation of the Seas arrived in a port in the southern province of Ba Ria-Vung Tau for a one-day tour on Tuesday, bringing more than 4,300 visitors.
The 18-story cruise ship called at Phu My Port during its first trip to Vietnam.
The guests, mostly from the US, the UK, Canada and Singapore, were received by Vietnamese travel company Saigontourist for a one-day tour around Vung Tau Town and the neighboring Ho Chi Minh City.
Operated by US-based cruise line Royal Caribbean International, the vessel is one of the line's three Quantum class ships.
It is 348 meters long, weighs nearly 169,000 metric tons and has more than 2,000 cabins for 4,905 passengers.
Last year, another cruise ship of the line, Quantum of the Seas, also docked in Ba Ria-Vung Tau Province for its nearly 6,000 passengers and crew to go on a day tour.
Saigontourist, Vietnam’s biggest tourism company, said it has brought onshore more than 120,000 cruise tourists this year.
