Really get to know the crew and reward them with tips when they've really helped you out. They work HARD for a little bit of money and they should be recognized with praise and tangible cash whenever possible. Some Australians (who don't do tipping where they come from) actually advised us to have our cabin gratuity charges removed because the crew is well paid. I disagree. Also, if the captain opens the bow of the ship for viewing, it's a good experience once. Get your photo with the ship's bell and that will be fine. It's deck 4 forward and you get there through the main theater backstage.
