Yes, I did one with additional stops including Reykjavik. Wasn't impressed.  
 
	The ship isn't particularly luxurious, the food is average and I was in the grill rather than the main restaurant, even in the height of summer the North Atlantic is cold and wet a lot of the time. Entertainment is poor. 
 
	Might have enjoyed it more if I'd had my week in New York first then travelled back to the UK cos the week in NY was hectic and the dullness of the crossing might have been more appreciated.
