Having sailed on the Sea Princess just 18 months ago, I was assured that the "sister ships" were identical. Sadly this did not prove to be the case.Princess would be better served spending a little less money on their new super ships, and spend a little more on making the Sun Princess more passenger friendly.Maybe we were just unlucky with our cabin, which had a few problems. My major disappointment was the time it took to resolve the problems.This was a repositioning cruise to Yokohama, but I felt that there could have been a stop between Sydney & Darwin. Six days at sea was a bit of a stretch at the start of the cruise.The staff, as always were great, but the process of getting passengers off the ship for shore excursions, particularly by tender, needs a bit of work.The loss of power while we were at anchor off Benoa was a major concern, and I really felt that there was a general lack of communication within the ship most of the time.Having said that, I'll be back, but probably not on the Sun Princess.
