Luckily, I don't have sea sick so I was ok.
It didn't work though.

The veranda help twofold. 1) Fresh air does wonders for sea sickness and 2) being able to see out over the sea to the horizon helps.I don't know what I would have done without a verandah because that is what made my "spins" stop so that I could get some sleep.

You will be fine as the weather reports and the captain will help you stear clear of all heavy seas.

Apart from sea sickness, was anyone nervous because of the movement, just as some people are afraid to fly? The reason why I'm asking is that my mom refuses to come with us because she's scared of the rocking of the boat. She won't get on a plane, either. I fly just fine, but now she has me thinking about the boat!

I actually like the rocking and sleep very well on cruises. I think if you feel sick the best think to do is go by the pool area and get some fresh air, it always helps. The waiters also told our tablemates who were feeling queasy to eat. An empty tummy made you feel worse than one with food in it.For me its the waiting for the shows to start. You can kinda tell that the curtains on the stage are moving. Not much (usually) but it's enough to make me feel ill. If I'm not looking at those curtains I do fine, so I either sit there with my eyes closed until the show starts or sit sideways and talk to my family (or our new friends from dinner - it seems like we usually sat together at the shows)I could tell the boat was rocking during a couple of the shows in the wtd.
