As someone with cruises booked on Saga and Fred, I can say Fred is quite a lot more expensive for what you get - having to add on transport and tips alone, neither of which are optional. Where Fred win however, is their choice of itineraries and ports, only accessible to smaller ships. I have also heard on the grapevine rumours Saga are considering a third new build, powered by hydrogen. On my recent Baltic cruise with Saga there were a substantial number of P&O refugees looking for the type of cruise P&O used to offer. I didn't hear anyone say they would return to P&O.
