Could anyone tell me if there are other cruise lines offering an itinerary similar to Crystal Serenity's Dover to Rome? This itinerary includes Dublin & Cork, Ireland, Oporto, Portugal, Lisbon, Gibraltar, Barcelona, Cannes, Florence, and Rome. This itinerary is just what we are looking for, but the Serenity is sold out except for the balcony and penthouse levels and we really aren't into black tie and formal evenings anyway. We love Oceania's ship size and their open seating, country club casual style. Any suggestions would be appreciated.
