This all sounds good. BUT if you break your hip or have another serious health problem ie heart, an ambulance will be waiting at the next port and you will be taken to the nearest hospital. The ship will sail on. Have been on a world cruise with Princess and have booked for another big one for next year. They are good - but not that good! Clever advertising Princess! Also, did you know that people die on cruises - the word was that about five died on our cruise. Princess has a small morgue on board, but they will never release the number of people who pass away. Have never seen anyone buried overboard. Would question if it ever happens???
