From what I understand (and have experienced cruising the Navigator at different times..) Giuseppi and Fabrizio alternate as Hotel Director. Fabrizio is on right now, and Giuseppe goes back on board May 18th. Jarl Jarlsen and John McNeil alternate (John McNeil goes back on May 18th). Gerry and Roberto and Monalisa and Alex were all still on in February, as well as Gilbert, Monalisa's husband. Gerry was alternating his entertainment duties with another fabulous singer named Pietro. Danilo left the ship last year, he's working in Italy, not as an entertainer. I'm sorry, I don't know Mohammed. Pedro the bartender and Roger (the old sommeilier) and Danny are also still onboard, and of course, "Elvis", as well as Miki the Maitre'D (but I've missed him my last two cruises he was on break). There are a LOT of the old Diamond crew on board! Which is why it's so fantastic!
