This is interesting we've ridden LM in DCA, and I'm not sure we'll bother in WDW when we go in May. My biggest beef with LM is Ariel,I agree with PP that she just looks so weird. Ursula is great though. I have mixed feeling about the ride in general. Little Mermaid was one of my favorites as a kid, so I was really looking forward to it, and rode it the summer it opened with no wait. Every time I've rode it I haven't had to wait. That's why I'm not sure if we'll bother with it in MK. It's fun, but wouldn't wait more than a few minutes.
BTW Yes Ariel no longer has ice cream cone hair in the Under the Sea scene in DCA, they attached an odd pony tail to the back of her head instead, and camoflagued the side view with some seaweed.
