Prices are only slightly higher, our flights were included, and yes you have to tip, or should I say they are added to your account ,you can of course have them taken off . Konningsdam is two or three years newer than Britannia but it felt like it was new , everything worked (toilets etc) and full glass shower cubicles in the staterooms which felt quite plush, drinks prices are higher than P and O however we were put on the have it all package before boarding (nice surprise) and allowing for our obc we came off the ship with them owing us money!!!! Which they paid into our account the next day. The one small negative was the MDR as the choices were at times bizarre but the ship, the decor , the service and entertainment were excellent
