I agree. Astro Orbiter is the best. The others are all identical to each other with different fiberglass pieces on the ride. The height, "arrival sequence" and placement of Astro Orbiter makes it by far the best.
I voted Astro Orbiter, because it goes far higher (thus giving great views of Tomorrowland) than any of the other Dumbo style rides.
I like Dumbo because it is the first Disney ride I ever rode way back when I was 4 years old. Plus it's a classic.
I have never been on The Magic Carpets of Aladdin or Triceratops Spin, and IMO they should have never been built since they are basically the exact same thing as Dumbo.
Astro Orbiter; although, as a kid, I was always afraid I'd fall out; they only had a thin, loose piece of material "holding" you in, and because I was small at the time, I'd slide all the way to the outside of the "ship". Scary! Yet I kept coming back. The only thing I hate is the long wait for the elevator.
"We are the change we've been waiting for! Yes we can!"
Would you all believe that I never got to ride Dumbo, but I always wanted to. The one and only time I went as a kid just, don't remember why but just did get to probably ran out of time. And everytime I have gone now as an adult, the line is always too long. But I have did ride the Astro Orbitor twice, once at 8 and then 20 years later, and I felt like a kid again so that got my vote for my favorite
Never rode Aladdin's Carpet or Triceratop Spin either.
