Marvgirl;
If my daughter wants to take us on a cruise, we are there.

I don't care where or what cruise line. You know us people in our late 50's get set in our ways. My DW and I love Carnival there really shouldn't be a big pary crowd on the cruise. No big holidays, or schoolbreaks. That is why we cruise after the first of the year, and before spring break. Too many people hear things from others who don't really know what they are talking about. The thing about Carnival is you can always find a party, or a nice quiet place to enjoy.
Keep trying , you can bring her around.

PS If it doesn't work out with your parents, we can pretend for awhile
