What type of accommodations do you usually have? How do you feel about them? I've visited some of Carnival's older ship ( a while back), and they seemed to have a lot of plastic stuff - chairs, sofa coverings, etc.
Hello Mainecruiser, These days, we almost always book a verandah cabin. (Just spoiled I guess.) On the newer Carnival ships, the "plastic" is not so prevalent. But they still seem to stick with "orange" in the cabin. Orange carpet, orange bedspread, orange curtains, orange sofa (vinyl not cloth). It my one complaint about Carnival. JMHO, I don't much like orange.
But the decor throughout the rest of the ships, while still kind of gaudy, is not nearly as bad, nor as neon, as the older ones. Some areas are actually quite attractive.
Over all I like Carnival. Not as much as other lines, but we've sailed with them several times and are going again in about 40 days. They give an excellent value for your money, very good food, very good service, (and free anytime ice cream. You gotta love that.
)
I've never tried NCL so cannot compare. Good luck with your choice.
