I am currently on the Island Princess. I have cruised on over 175 cruises, including three World Cruises. Favorite lines and last four cruises have been on Regent and Crystal, although I have probably been on most lines over the years.
I am extremely pleased with the Island Princess. She is an older ship, her decor is somewhat dated, but she is very clean and comfortable and service is excellent. The food in the Bordeaux dining room has been very good. The entertainment is excellent and live music is abundant all around the ship. It is not in the luxury category, but I would not hesitate to book this ship again. Also, the cost is a fraction of what it cost to cruise on Crystal, Regent and Viking.
