Splash Mountain and a few drops of water are fun even when it's 40 degrees and dark outside. There is not nearly enough water to soak a sweatshirt or jeans (if the weather requires such). And Splash with it's story, music, characters, and length is in my opinion the best ride in all of Disney World.
The problem with Kali is at least a couple of people on your raft will get absolutely soaked and there's no way to know who it will be. In a temperature under 75 without a poncho or full change of clothes this could be potentially be a day ruiner, lol.
