We have traveled on both the Allure and Oasis of the Seas with RCI and Solstice and Millennium with Celebrity. Compared to them Princess is unfortunately a way way distant last. First and foremost the quality of the cooking in the main dining room and even the Crown Grill is poor at best and downright disappointing. They had excellent produce in the freshest seafood and quality meats and sadly in the hands of a rank amateur cook - totally wasted. Everything was way way overcooked and dry. As I mentioned we even tried the Crown Grill one night to get away from the Main Dining room but that didn't really fair much better - what a sorry waste of $29 per head.
We always chose Anytime Dining so we could sit by ourselves and not have to share. With Princess Anytime dining simply means you don't have to arrive at the designated times of 530 and 745pm. They don't really allow you to book - so you turn up when you want and get treated like a second class citizen when you politely (and this was every single sitting for dinner and several lunches and even afternoon tea) decline to share - which is the first question that gets asked.
Best of all every time we were eventually allowed to enter the dining room, half the place was empty and I could always see a whole row of empty two person tables so I'm not sure what the fuss was all about.
We also specifically chose Princess even though we have never sailed with them based on the information provided regarding their expert talks and knowledge about Alaska otherwise we were going to try Holland America. Sadly this really didn't eventuate either. On the second day after leaving Vancouver at the crack of 9am they had an expert Alaskan lecture followed by how to raise a family in Alaska around noon which I wasn't particularly interested in. They had the much advertised Iditarod champion on one of the port days at 3pm which we missed as we didn't make it back from the shore excursion in time.
Lastly they was a total distinct lack of activities (or poor timing during the afternoons) when nothing was really on offer other than the obligatory art auctions or shopping promotions. Compared to RCI and X they had much better timed activities during the dull afternoon periods whereas Princess piles on the interesting stuff during the night so you cant get to them or they overlap one another during the peak times. Why couldn't they simply move some of them to the afternoon?
So in summary this will be our first and only Princess cruise and back to RCI or X for us.
