A cruise book that I just finished ready commented that the standard cabing on the disney cruises were the equivalent to the suites on most ships. It said Disney offers the family-friendliest cabins around.
I've booked 2 cat 10 rooms for my family of 5 for this November.
This was cheaper than getting one cat 4 suite. I kind of like the idea of having 2 toilets and separate sleeping areas for the kids. It will be interesting to see how it works out.
