I have never had a bad experience with them.
I understand other cruise lines have had problems, such as Carnival - which I would never sail on. I have no desire to sail with low-rent jackasses (I'm talking about the passengers, not the crew).
As with all things in life, you get what you pay for. When it comes to vacation, I don't go cheap. Life is too short to have a miserable experience on your vacation.
It's amazing how big these cruise ships are getting though. The ship is now the destination. Who cares what port you are in when you are in a ship of that size? Sometimes I just stay on the ship when in port. Much less people crowding the ship means you have even a better experience doing things on the ship. You get the pools to yourself and you get much more attention from the crew.

We pretty much do that now, too. The ship is the destination and we actually like at-sea days.
