We love the idea of a couple of nights on the water, and some of the tours are built around a Mekong Delta cruise while others just do a day visit. We’re trying to work out if the overnight cruise is worth prioritising. Was the Mekong cruise a highlight for you, or more of a nice-to-have?
If you have time, you should give 1 or 2 nights for the Mekong Delta.
Otherwise, a day trip is also fine.
