Aladdin being one of the most popular Disney rides deserves a better fate than the carpets. I agree with keeping it, but moving it somewhere better like DHS or even Fantasyland somewhere. Whether people like it or not there is something magical about riding a spinner ride at WDW compared to your local fair. People love it, although I have never done anything but practically walk on the carpet ride so the lines are thin.
Maybe Aladdin gets a dark ride where the old Snow White was located. Who knows? It earned more than a Dumbo clone though. Then again, that's all Dumbo got.
