Looking at it logistically only, if you're going from AK, then Raglan Road will be easier to get to, assuming you park in the right lot (I think lot 4). If you go to Morocco, you have to park, get to the gate, go through security, then find your way to the back of the park. With the ages of your kids, the less walking the better.
On the other hand, the show at Morocco is entertaining, and the dancer often engages the little girls in the crowd to come up and dance with her. At Raglan, the entertainment doesn't start until later (often 9:00, I believe) and, while lively, is focused on pubgoers more than little girls.
If you're worried about holding double ADRs while you decide, note that you can book Raglan on Opentable.com for Orlando.
The food at Raglan is good, and that at Morocco is decent, but portions there can be small. I enjoy both, and on reading this post realize that I may have been of no help to you whatsoever . . . .
