First cruise with Princess after using many, many other lines. Getting on wasn't bad, but getting off was a long, waiting nightmare. Theoretically there are people who will clear away unused deck chairs, but in four/five days we never ONCE got to sit on the deck: people would come up at dawn and throw a towel across a couple chairs and then never return.
There is apparently a very loose dress code for dining; worse, it is unevenly applied. Some clothing passes, almost identical clothing doesn't.
The waiters in the dining room were incapable of getting ANY order right. We finally gave up. Ordered a 'late harvest' wine ($4), instead got a port, which we sent back. Showed up on the bill as over $11. Complained, they reduced the price to $6, which of course was still wrong.
