Just off Meraviglia, diamond perks were Specialty Dinner (so happy that is still there!), bottle of Prosecco, macarons, four wrapped filled chocolates, priority boarding/disembarkation, invites to diamond party and another for all levels (we did not attend either), there were probably some discounts or a few other items that we did not use. I was disappointed to not get the chocolate ships but did enjoy the things that we received.
