I sailed the Island Princess for two weeks this spring to Alaska and just loved it. I will be sailing the Sapphire Princess, sister ship the Diamond in about two weeks. One of the things that I like about the Diamond is the fact that it has Skywalkers which is a very attractive area and a great place to just relax. My personal choice would give a very slight to the Island over the Sapphire but would sail either one in a heartbeat. The passenger capacity on the Island is about 1970 passengers and on the Diamond it is about 2670.
I also would wonder why Princess would take any ship out of service for refurbishment and then sell it. Can anyone tell me where this information was found?
Enjoy your cruise as you are in for a fantastic cruise on either ship.
