When I come off Kali soaking wet, it's because I've ridden it a few times in a row. I've never gotten completely soaked on one ride.
The Popeye ride at IoA on the other hand... They do not want you getting off that ride with a dry spot on you. It's such a fun ride though, so much better than Kali.
I rode Jurassic Park last night, front row, center seat, and didn't really get wet. My butt did, but most of that was because no one had ridden in the boat during the ride before I got on, so there was a a puddle of water on the seat. Weight might have had something to do with how big/small the splash was. I was the only one on the boat. Probably the only one on the whole ride at the time. The Uni parks are awesome in the hour before they close. Ghost town. Everything's a walk on. At IoA last night, I did a full circuit of the park, riding Dueling Dragons, Forbidden Journey, JP, Spidey, and Hulk from 6:00 to 7:00. 5:30 to 6:00 at the Studios was Rip Ride Rocket and Despicable Me (which sucked up most of the time with various pre-show elements). Totally suggest taking advantage of this when you're over there. One park usually closes an hour after the other, so you can close up one park and head to the next for a bit.
