One thing I noticed is that although there was a sign at guest relations stating that they would not be able to make any cabin assignment changes because of a full ship, the ship wasn't at total capacity (confirmed by a CM). Keep in mind that every room has a maximum capacity. Not all rooms are filled to maximum. So, full is sort of a relative term. Don't forget, they build the ship and staff, etc. to handle it when it is full. It never really felt crowded on either of our cruises. And I agree with an earlier poster, above. You need people on a cruise to make the experience fun and festive. Have a great time.
