First item to budget is tips. For the 7 night cruise its about $75/person for the week (children included). This you can charge to your room. You will need some cash to tip the porters and port canaveral on both embarkation and disembarkation days ($1-$2 per bag). If you have room service you should tip the person that brings you your food (you can now charge this to your room or you can give them a couple of dollars).
For us shutters is our downfall and we can easily spend $200
If you drink sodas you can pay per the glass or buy a refillable mug ($35). Soda is free at the sit down lunches and at dinner.
Smoothies are a chargable item.
Alcoholic beverages always carry a charge. If you stick with the "drink of the day" you can save a couple of bucks per drink. I believe that the drink of the day costs $3.50 to $4.50 (I just remember seeing the signs - I don't drink)
If you play bingo you can drop a lot of $$$ fast. There are different "packages" you can buy when you go. I only remember the $35 one (good for 6 games I believe, others can correct me).
If you have kids (or DH) that likes video games you can buy arcade cards in $10, $15 and $25 increments.
If you enjoy wine with dinner they sell two different wine packages ($145 and $265) - or you can buy a bottle or glass at dinner.
If you are interested in the spa and the prices try this link:
CastawayClub and click on the SPA link and they will give you an idea of services and prices. I couldn't find anything about these on the official
DCL site
Souveneers: To me they seem extreemly overpriced but we buy some anyway. Others will be able to help you out here better than I.
And then there are the excursions. Go to
Fun Onshore for descriptions and prices for excursions.
Bottom Line: Except for TIPS you can get by with spending no extra money and you will still have a wonderful time!!
