I've been thinking that a European river cruise (maybe 5 days, not during summer) would be a good holiday for us as a family group (2 x pre-teens, 2 x parents and 2 x 75-80yr grandparents).
I've never been on a cruise but I like the idea of boat travel (ideally we'd get to the start point without flying), and both my kids and my parents love a city break. My parents' mobility is a bit of a consideration now though, and I'm conscious that they don't have the energy to do full-blown exploring everywhere they go, so wondered if this kind of holiday might take the pressure off a bit.
Has anyone done this with a family group and would you recommend?
