lucassidy:How much are fountain cards for a five day cruise?
The price is $6 per day for an adult and [I believe] $4.50 per day for a child.
You pay 15% on top of this for gratuity [and then are tip-free for the rest of your pop-drinking]; additionally, if you purchase the thing while you are still in port on the first day, you will pay whatever local sales tax applies.
And, as others have said, if you drink more than 3 glasses of pop/day, then it is cost-effective.
Desperately seeking 10th cruise for the free laundry.
