I was in my 30's and still had fairly young kids, but they were old enough to appreciate cruising and have cruised in their adult life as well. Just something about the whole expierence that makes you wanting to do it again and again...
When I was eleven years old my Parents and I came to the USA on the SS Olympia. It was was like cruise. They had entertainment, a pool and plenty of food.
The first cruise tha I booked myself was in 1998 on the Celebrity Century and I have been hooked ever since.

I was 60 (!!!!) because the idea of cruising had never occurred to me. We decided to do one because we'd never been to Alaska, and because we were looking for a vacation we could do with our now-adult-and-married kids and their spouses. It turned out to be a perfect choice and I started planning the next one (Panama) right after we got home.
The "kids" have now done three more cruises themselves, and one has introduced his own children to cruising. Addict 'em early, that's become my motto!
I was 45, but the DW beats Holly, she was 11 - she had to suffer with me a long time before getting to take cruise #2
