Some additional suggestions for first-time cruisers:

Do your math before taking out a beverage package, alcoholic or otherwise; don't get one if you won't drink enough to match the daily breakdown.

Arrive early for shows for good seats. Don't forget to reserve in advance if they ask for it.

Don't buy the photo packages. Take your own.

If you can swing it, go for a room with a balcony.

Excellent article!
