We chose this pricier cruise as a treat, expecting high levels of service and choices along the way. We were patient with rather shambolic service, as they were a new tea, and very pleasant.
Odd noises specific to our cabin caused disturbed sleep, but we were about to enjoy a change of cabin when the engines broke down( it had only been in service for 10 days since lockdowns).
We couldn't dock in 2 ports, missing out on city experiences which are rather the point of river cruises.
Fine, when the intrusive noise in ours was sorted/we were moved.
