Sailing the Sea will be a different experience from the Sun Princess in many ways. We love the Sea but not for the same reasons we love other lines and ships. We love her because she is smaller, the crew is exceptionally friendly and the itinerary is great. As for ages and home states of those sailing with you; the majority of the ship will be from the southwest and mid west; Tx, OK, NM, La, etc. They will be very down to earth and most will not be expecting a 5 star experience. The age range will be, as it is with most NCL ships, very diverse with the average age being mid 40s to early 50s I would guess and the number of children will be far less than during holiday or summer time. Hope this helps a little. Have a wonderful time.
