They charge on the Century and Galaxy except for suite passengers.
I had a medical problem and within 2 visits to the pool I was cured.
I dont know what they put in that water but,,,,,,,,,, it was incredible!!!
I dont want to list my condition but if anyone is curious, back channel me and I will share.
Highly recommended. I have pics of the pool in each ship if anyone wants to see what it looks like.
