where is this information coming from that Princess attracts an older crowd on its 7 day Caribbean cruises? Not true at all. Good mix of all ages. The longer cruises on the smaller older ships are the ones that tend to attract and older crowd, but even at that there is still a mix of all ages.
We sailed on the Dawn's sister ship the Sea Princess and loved it. Plenty to do at night- good shows, always a band playing in the smaller lounges and the disco gets going after 11pm.
