Had not been on the Sun Princess but found it pretty much like the Sea Princess both inside cabins are far to small.. prefer Golden Princess as cabins are larger and so is the ship.Not enough public laundrys or they should be left unlocked so people can use them anytime would, prevent disputes there..the ships are all very old,tired needing a lot maintenance and Princess should be replacing them as the cost of these cruises warrant better ships . Prefer to have longer cruises as I enjoy cruising and Have a good time on every cruise as it is only as good as you make it. Very friendly helpful staff mostly food was very good wherever you choose to eat. Shows were of a vey high standard some of the best I have seen on the 13 cruises that I have been on. Looking forward to the Majestic Princess coming next year......
