My family is going to be taking a cruise to the western caribbean next summer. We have 4 kids who will be 14, 6, 3, and 1 years old when we travel. When I try to book it online it won't let me have more than 2 kids in a room. I was really hoping we could all be in one room (a delxue family oceanview room). Is this possible? Even if it is possible, is it going to be too crowded? Should we just get to rooms? This is our first cruise so we aren't quite sure about size. We were figuring we would bring a pack n play for the 1 year old to sleep in.
