Its been a couple years, but at that time they offered the dolphin touch or dolphin swim. We chose the dolphin touch because of the difference in price.
It was a quick touch and it was over, so do the swim if offered. The bus transportation from the dolphin swim area and the falls, was good and smooth. The falls were great. Bring a water proof camera for pictures. The rocks are slippery and its a good way to ruin a camera. Also wear aqua socks, flip flops don't work that well and going barefoot is questionable.
