My husband and I went on our first cruise in October on RCI and we LOVED IT! Now we want to take the kids. Problem is, we have 4 of them The cost of a cruise for 2 is way more affordable then 4! I just tried to check Carnival and it won't even let me put 6 people in? Says only 5 can be booked at a time? Any tips or tricks for me, to make it affordable?

Our kids are ages 9, 7, 6 and 3 ....

TIA!
