We have not used that Club, we have used the one at the GF twice and the kids love it.
We will be trying The Cubs Den at WL, The Sandcastle at the BC and Simbas at the AKL this upcoming trip.
Our kids love doing the clubs in addition to all of the wonderful things our family does together. They actually requested to go more than once this time. So... we booked 3 nights out of our 9. They are 5 and 6. I think they enjoy some down time playing video games and watching tv.
