Things to think about....
Do you need bottled water? The ship's water tastes great. If you still want bottled, do you want to bother getting a case at your local grocery store ($3.99 for 24 on sale here this week) or do you want to spend $30 for a case on board?
How many photos can you take with your camera vs. how many do you want to buy? Cruise personnel will take a picture with your camera at the same time that the ship's photographers are taking their picture to sell to you.
I really like the board member who compared cruising to having a child...you can do it on the cheap with hand me down clothes, used crib, etc. or you can do it on the high end with everything new and top of the line. In the end, you still have a child, and particularly in the beginning the differences may not be significant. There are lots of ways to spend money on the ship. Only you can decide which are important to you and where a cost savings will not affect your enjoyment of the cruise.
Do you need soda outside the dining room, or is having it available at 3 meals a day enough? You can drink juice, fruit punch, milk, hot chocolate, lemonade, and iced tea free at all times. Or, do you want to put a 6 pack in your luggage and keep it in the fridge in your cabin???
Do you need the internet package or arcade cards, or do you get enough of this at home?
You get the idea. Prices are available on line at the
DCL site (some) and at
