The H20 pass is a combo pass where you receive 1 x hour on the Cable and 1 x hour on the Aqua Park.
Your first hour will be on the Cable (where you will need your strength!).
When you purchase your ticket you have the option to have a 1 x hour break in between the 2 activities or go immediately on the Aqua Park for your 1 x 50 Minute session.
The H20 pass depending on whether you have a break in between or not runs for 2-3 hours.
