I did 3 Croisi river cruises & 1 barge cruise last year & is definitely a value option but is a very different cruise experience to Vantage. Firstly in our experience we were only part of a very small group of English speakers onboard,the majority are French & the language barrier is very evident.
The food is ok being what the French eat & not what I would call gourmet.
The cruise staff look after the English speakers & we mostly had English translations on the shore excursions but at times wasn’t as much as the French received. The entertainment is focused on the french so not easy to relate to. They do have free drinks,coffee all day & night. I’m booked on a river cruise in November & will continue to cruise with them. So just be aware is a very different cruise experience to Vantage which is tailored to the American market whereas Croisi is for the French market.
