Dining rotation w/ kids

I was reading in a travel book about the dining rotations for the 3 night cruise. It gives samples: one with adults only, one with young kids and one with older kids. My question is, what are the age groups for the young kids and older kids? My girls will be 8 & 9 when we take our cruise. They are also very well behaved little girls, even when they are excited. I was wondering if we will be put with babies and toddlers or with the older kids. My mother and father will be with us (more than likely) and maybe my sister and BIL and my niece who will be 14 when we cruise. Sorry for the rambling, I just didn't want to forget all the details.:mickey:

A few years ago, this was a popular way to try and figure out the dining rotation ahead of time, but it's not really accurate anymore. You're just not going to know until you arrive and pick up your room keys at check-in. If for some reason, you have your heart set on a particular rotation, you can stop by the area they have setup for dining changes and see if there's anything they can do for you.
