It is unlikely you will notice any motion on today’s modern cruise ships. All ships today have stabilizers to smooth the ride, but if you are motion-sensitive, a mid-ship stateroom is recommended. And, if the seas do get rough, there are many preventative medications available on board. River cruises rarely encounter any rough seas at all, and are often a very safe bet. Your Sea Courses Advisor will be able to guide your booking to what accommodations or itineraries best fit your desires and concerns.
