Another thought - isn't it funny how people aged 30 are still considered "kids" these days? This is not anything to do with Seabourn - just a general comment on modern society.
I have not been on Seabourn in over a decade, but I have been on lux lines. If I went on any ship and heard anyone complaining about "those kids over there" in reference to 30 year olds I would be shocked.
I guess there are some people who live in Sun City and don't want to see anything unless it is related to golf and early bird buffets - but most people "of age" I know appreciate having younger people around.
