If your from New England you won't like the lobster. What they serve on cruise ships is not a "true" american lobster (just a name not the country).
Two kinds of lobster-like crustaceans exist in U.S. waters: the “true” or American lobster and the spiny lobster. The true lobster has claws on the first four legs, and is only found in northeast waters. The spiny lobster; the spiny lobster has a pair of horns above the eyes, lacking in the true lobster. The item marketed as “lobster tail” usually is a spiny lobster. The spiny lobster is found in warm waters off Florida, in the West Indies, and off southern California.
Many people obviously like the taste of the warmer water lobsters, but if you're from New England, you will really notice a difference and it won't taste right at all.
