I'm an equal opportunity cruiser, having experienced many of the Caribbean lines including Carnival, Norweigan, Holland America, Royal Caribbean, Celebrity and Princess. I have stuck with Princess for the last few years because of the multiple evening entertainment options including multiple choices of live music, nightly comedian or unique acts and an overall lively nighttime experience. I have noticed in the last 2 years, both the quality and quantity of entertainment options on Princess has deteriorated. It seems that Princess is choosing to save money by eliminating entertainment options. I just returned from the Star Princess on a 10-day Caribbean cruise, and they did not even have a caribbean band on the ship. Not once did I hear any caribbean music while sailing the caribbean. I cannot express how disappointing this was, as I love to dance to the steel drums and hear Bob Marley. Imagine sailing away from a beautiful caribbean island to the sounds of poolside elevator music.Although there were many passengers in their 30's, 40's and 50's, the live entertainment was clearly designed for the over 60 age group. It appeared that to save money, Princess chose to show movies both on deck and in one of the best venues instead of offering live entertainment. The sad thing was, because the live entertainment was so bad and so "old", the only thing to do was go see the movie. They also had "ballroom dancing" everynight until 8 or 8:30 with piped in music in the best venue on the ship - not even live music. In cruises past, there have been live bands in this venue. Yet another cost cutting technique is to break up parts of the Princess band/orchestra and place them in different venues, calling it "special entertainment".I was also very surprised at the lackadaisical service. My cabin steward was so overworked that she barely touched my room each day. I was left with wet or dirty towels hung back on the rack on several days and had to beg for ice in the bucket each day. In the buffet area where I went for dinner several nights, no one ever asked if I needed water or would like a drink - I think I must have been invisible. I would see the staff huddled around together chatting, but rarely paying any attention to the passengers. I'm not usally bothered by this, but it was so noticable that they just weren't engaged whatesoever.What I love about Princess are the great itineraries. The ports on this cruise were fantastic. But with 3 days at sea and each night on the ship, Princess needs to improve their entertainment offerings if they're interested in attracting any passengers under the age of 60. The ship, the service and the entertainment are how they need to differentiate, and after this cruise, I would say they fall short on all three points.
