Jamie alternates with John on Voyager. Both excellent. Interact with guests frequently. Both lead many activities. Barry is alternating with ??? on Mariner (John has been on Mariner in past). Barry is the best of all CDs. He doesn't host as many activities but he is omnipresent and always interacting with guest. Sam and Giuseppe have been on Navigator. Giuseppe is a favorite of the women. I understand that Paul will be taking over for Sam since he is leaving. I don't know how Paul will do as CD; he was wonderful as Assistant on our last cruise.
