Bui Thi Bich Thuy, 38, said she used to travel more than 100 km from HCMC to Vung Tau and then take a high-speed boat to Con Dao, which would make her really tired.
The only other option was to travel by air.
"I feel happy and excited as the HCMC-Con Dao vessel has finally been put into operation, helping to reduce travel costs. The tickets are nearly 50% cheaper than airfares, and the travel time is only a few hours."
Tickets, sold by agents and at ticket offices and websites, cost VND615,000 - 1.1 million (US$24.16-43.22) depending on ticket class and departure time.
