Yes, the Little Mermaid ride at Disney California Adventure just reopened with many improvements and additions. The biggest being they repainted all the characters in the main room, and now use blacklights to make the room darker, and have more of an under the sea feel. Disneyland guests (Annual Passholders) have been complaining about the lighting not being what it should be since the attraction first opened. Disney apparently responded to the complaints to make it better.

I haven't been over to the park since it has reopened, but look forward to seeing it for myself. Also, more characters have been added throughout the ride to fill in some "dead" spots. As well as some adjustments to the look of many of the main characters at the end. No telling if Team Disney Orlando (know to be cheaper) will spend the money to do this in Florida.
