In reading many NCL boards it seems our cruise starting in Rome on May 20 has people boarding and departing on different dates. Some people will already have boarded in Barcelona and I'm assuming getting off when we go from Rome to Barcelona. (Hope that's not too confusing.) As a result I'm finding no roll calls for our cruise but one for the cruise before us on May 16 - May 25. I even tried to start my own roll call board with hardly anyone joining. Is this typical to have people coming and going on different dates? It seems crazy to me. We've been on 4 other cruises, (not NCL), and never experienced this nor have I never had a roll call for our cruise. Thanks for reading!
