I realize that everyone is different; but, I am very prone to motion sickness. Can't ride in the backseat of a car, swinging bridges, rocking chairs, .... That being said - we have been on 3 Disney cruises and I have never gotten ill. We've stayed mid-ship, aft and forward. Always had veranda and if I started to not feel well, I would just open door and not look at the rushing water. Always felt better w/in minutes. The thing I also avoided was not watching the water go by as I'm walking on the deck. Now the excursions were a different thing. I was willing to swim back from St. John to St. Thomas! I got very ill on the small boats associated with the excursions. I was taking Bonine (like it better than Dramamine, JMO) and loaded up on ginger capsules and drank lots of ginger ale. Hope this puts your mind at ease.
