If you or anyone in your group is small, make sure they don't sit at the front of the banana boat. My side of the boat was flung off once, (just to let you know, the water isn't deep, so don't panic if you get thrown off), but for a good 2/3 of the ride, my mom had to hold onto my life jacket as I keep lifting off the seat.I was holding on (for dear life) so tightly that when we got back to shore, I was shaking so hard I couldn't walk.
Just make sure any small people are in the middle seats. It might make for an easier ride!
