Expect an international mix of French, British and American passengers, plus Australians and New Zealanders. Most passengers are mature, well-traveled and looking for an authentic experience where they will get to meet local people and become immersed in Asian culture.

Not too much. Heritage Line does not have a dress code, and passengers need to bring cool, comfortable clothing for the warm weather conditions. Some passengers put on something a little smarter for dinner, but that will be smart casual, rather than anything overly dressy.

Mostly. Fares include all meals; wine and beer with lunch and dinner; and mineral water, soft drinks, juices, tea and coffee throughout the day. Also included are shore excursions, yoga and tai chi classes, onboard entertainment and Wi-Fi. There is a charge for spa treatments, and crew and guide gratuities are not included.

Passengers look forward to authentic and culture-rich tours that take them to the heart of each destination, including visits to temples, rickshaw rides and village walks.

Signature activities onboard include informative lectures and workshops on local culture and traditions, cooking classes, performances by local dancers and the opportunity to take part in tai chi or yoga lessons.

Best for: Luxury cruisers looking to explore Asian rivers in comfort

Not for: Families, budget cruisers or anyone wanting a packed list of onboard activities
