I had forgotten about Jumpin' Jellyfish and Golden Zephyr. I wouldn't do Golden Zephyr again (pretty dull), but Jumpin' Jellyfish was worth riding once. The ride itself is very tame (it's a baby version of a drop ride), but I did enjoy riding it at night facing into DCA. It gave a pretty nice view of the park with all of the lights on. I wouldn't do it again during the day, but nighttime was worth doing at least once. You get much the same view (even better actually) from Silly Symphony Swings, but for folks that don't do spinning rides very well, Jumpin' Jellyfish is a good alternative for the view. I guess by the same token, the Carousel and Dumbo are two other rides that I probably wouldn't do without a little one. I think both are worth doing, but if you're pressed for time, I would probably forgo those if there aren't any toddlers in the group.
