We would like to stay at one location on a French river and take day cruise boats up or down river to view the scenery. So, a day-only boat, not one where you stay overnight.
Which section on which river; has a section with attractive villages/ cities/country vistas and is well-served by frequent scheduled cruise departures. Not close to Paris but preferably locations well-served by train to a major airport.
What term do they use to describe day cruise boats in France?
What is the name of the main day cruise boat companies?
