I am doing it three times - not on the ships I would prefer - looked for bargains so took what I could afford:
Alaska - on the Norwegian Wind in June
Northern Europe - on the Norwegian Dream in August
South America - on the Norwegian Crown Odyssey which I hear is the best of the three.
I would love to afford to go on Crystal Cruises on these cruises, but one takes what one can afford.
But I do love the Legend of the Seas.
