We are new to the cruising world & booked our 1st cruise on the Zuiderdam for Jan 5th for a 7-day Eastern Caribbean cruise. Going along will be 2 of our children (ages 10 & 14). Will there be enough to keep them busy & happy?? Any input about this ship will be appreciated. Cat/Cabin is booked for J/1068. Also, I have a very weak stomach & wondering if I'll get sick aboard the ship!
