Didn't realise that a revamp was in the works for the Jungle Cruise, the 'after-dark' version will be interesting to see!The revamped version of the attraction will have new lighting effects and other special show effects. In addition, a specially written musical sound track will be heard throughout the attraction for the first time in any Jungle Cruise. Also, an after-dark only “night cruise” will provide a unique take on the jungle adventure.
Can't wait to see what they'll be adding.
