Last week, Disney started removing lights on Cinderellas castle. the lights were put up in mid September
A quick look at a dry, Splash Mountain (will re-open later this year):
The exhibit reopened with the same theme (helps kids defeat unhealthy habits) with different characters and also reversed the order in which you entered and exited the attraction. Most of the activities are pretty much the same from last year's If you have enough energy after walking around the world make sure you check it out. It is directly behind Electric Umbrella in Innoventions. There is an optional scavenger hunt offered after the exhibit and everyone gets a free Habit Heroes band.
