We started the land part of our trip in Hanoi, joining the Harmony a week later for seven nights on the Mekong. I have sailed with Emerald once before (on the Rhine) and have been more than impressed on both occasions by the attention to detail of every aspect of the cruise experience.
The Harmony is a beautiful and relatively new ship, very tastefully furnished and fitted-out.
The main lounge is sizeable with picture windows on both sides, with plenty sofas and chairs, free coffee and (circa 8 varieties of) tea 24 hours and a comprehensively-stocked bar.
