Brand new, put into operation in May of 2015, cruise ship Mein Schiff 4 entered the harbour in Gdynia. On this occasion, memorial plaque had been set up in the Alley of Passenger Ships visiting Gdynia. I have visited few decks on this cruise ship. This presentations shows its greatest attractions: the entrance, main hall, restaurants, bars, audiovisual and theatrical hall. I have also visited SPA, sun deck and sports facilites. Photos are supplemented by a short but useful information.
