My daughter and I got there as the gate opened and ran to JTA. Took the first boat out, went on row 2, I told her about the water coming over the front. But it didn't happen because we we're the only ones in the boat, no weight. Later we went with a full boat and the water did come over the front. If you have big heavy adults in your ride, then the water will definately come over the front. If you go with a bunch of kids, you can scoot to the center and put your hands up to block the water if you know when it's coming.
Here's exactly what happens. After the first big drop, the boat takes a 180 degree turn, then drops into a moat. The front of the boat goes under water and it pours into the first row. As you go up the hill, this water moves to the back and soaks the shoes of these people.
Best tip, sit in row 2 or 3. If you sit in the back, hold your feet up when going up the hill after the boat goes into the moat. You don't need a change of cloths if you sit in row 3.
Even if you get soaked in the front, you'll dry off. It's your shoes you want to keep dry. It's the people in the back that need to keep their feet up.
