AmaWaterways is doubling capacity on the Mekong River in August when it launches the new AmaDara.
The 124-passenger vessel will be sailing seven-night cruises between Siem Reap in Cambodia and Ho Chi Minh City in Vietnam alongside the AmaLotus, which has the same capacity but smaller suites and lower deck cabins with a porthole.
During the cruise, passengers will ride in an oxcart and trishaw, visit monasteries, floating markets, museums and temples, and stay two nights in Phnom Penh.
October prices start from £1,818 per person cruise-only including local wine and soft drinks, wine with lunch and dinner and bottled water.
