In July of '12, when only the Finding Nemo and Cars sections were open, we stayed in a Cars family suite and loved it.
But, the prices were considerably lower, and I was a CM at our local Disney Store at the time so we also got a 60% discount.
When we wanted to book it again for our June of '13 trip, the prices had gone up considerably, and there were blackout dates for CM discounts during the time we were going to be there. It was just not going to be worth it to us.
We opted for a family suite at ASMusic (where we had already stayed in a family suite on our July of '07 trip) at a much lower rate, and were also able to use my CM discount. We liked it just fine.
As I said, we really loved our stay at AoA. Great suites, great food court, great pools, and theming.
If you can afford it, I'd say give it a whirl once, and see what ya'll think.
It is a neat resort...!
