Former Jungle Cruise Skipper here, I realize this post isn't quite timely but I just wanted to weigh in. As previous posters have said the majority of the lighting comes from spotlights on the boat itself. During the day, Jungle is a tropical adventure. At night, it's a bit more intimate. After the sun goes down, the line does as well, and if you go in the last hour the park is open or so, your family might be the only party on the boat. So, if you don't plan on having a Skipper talk to your family directly for 10 minutes (if you avoid participation etc) it can be awkward. But, if you're the only family, or one of the only families, it can be super magical! Your child might even get a special opportunity. But don't plan on photographing anything.
