Ellen's is long. Unless the kid really likes dinosaurs, she will probably be really bored. However, it's a great place to take a nap, because it's long, the ride cars have really long benches, it's dark, and the AC is great.
If your DD likes plants, then she might like the Land. Our DS rode it at 6 and said it was really boring. We haven't been able to get him to go back.
A 5 year old might like Figment. It's not scary, but it's weird. DS at 9 thought it was weird and boring. However, the interactive stuff at the end looked kind of cool, so we will try it next time. We didn't have time last trip to do that stuff.
I would pick Figment out of all of these for your DD, if you pick any. However, it's good to do every ride at least once. I bet Ellen or Figment is most likely to be replaced of the 3. However, there are no announced plans of them leaving.
