If I may share an idea with you who are questioned re:sea sickness on a cruise. I have sailed on a number of times with Disney and other cruise lines.

Personally, I have experience some side effects but not too serious and only if the water was rough in the area.

On the past several trips of cruising, I wore "sea band"s on my wrist. These are usually purchased at Target in the Pharmacy area. They work wonders and are assisting by using pressure points on your wrist. They are not expensive. The other suggestion is to buy a box of "Ginger Gum". Usually found at pharmacies. HEB stores carry it,I know. Anyway, it is pleasant tasting and if one chews two pieces (look like chicklets) on occassion, it helps.

Last,but not least, Dramamine will be available. I have found the wristlets and the use of the gum the best.
