"Wait a minute Paul, I could swear that we saw that show on the Atlantica in March."
The reason why you think you saw that show already is because ALL the cruise ships have basically the same show! That is the problem.
Hah - just kidding. You are right that Costa Atlantica has a show which is actually a "Salute to Italy" which has bits on everything Italian through the ages. In the end is a piece about papparazzi with Vespa motorscooters.
