Was on the Iceland Canada crossing. Very smooth but there lacked things to do for anyone under 50. Also had a worrying fire on board one evening over the tannoy telling us it had broken out in the incinerator room. Could smell smoke. Also had a person helicopter lifted off. All quite eventful! Boat was clean and tidy and staff very nice plus the food was great. The buffet was very good especially the sushi etc. Did get a bit of a dodgy stomach from the mussels which upset my stomach for 24 hours but it soon passed. The entertainment in the theatre was very poor however. Some of the acts were dreadful including the resident singers. A very good guest French pianist though. Overall worth the money but be prepared to occupy yourself as there is very little to do on those long sea days if you don't do ballroom dancing or enjoy bingo etc !
Being on the 6th floor atrium view we were below the buffet food preparation area. You could often hear them above cleaning and banging until 2am and they would start up again around 5am.
