While walking along a passageway on the Caribbean Conquest, at center I noticed a bump in the floor bearing a sign, "Watch Your Step." A year ago, on the Norwegian Spirit, there was no such bump. I asked my son about this. "Oh," he said, " this ship was built in Italy. The ship last year was built in Germany." It seems they build Caribbean ships in a naval shipyard as two pieces, then welded together. Italian craftsmanship - maybe they should stick to purses and shoes.
