We are trying to decide on a cruise. Having never before cruised we are looking at the 7 day eastern Caribbean cruise or the 5 day western Caribbean cruise. Both by Carnival. I prefer the 7 day choice but wife is thinking the 5 day might be better for a starter. She’s really worried that herself and the kids (teenagers) will get sea sick. So, my question is this. Do the smaller older ships have stabilizers and is there more of a chance in getting sea sick on a smaller ship such as the Imagination as compared to a larger ship such as the Glory?
