We've stayed at AoA and CSR. My kids preferred AoA and I preferred CSR. They LOVED the over-the-top theming. I loved the peaceful, relaxing feeling at CSR. The rooms were nicer at CSR, no doubt. If you're kids are young enough to get really excited about the theming at AoA, that would be my pick. The theming at CSR will seem like a disappointment if they love POP. Just my opinion!
