Had mixed feelings about this place but we ended up loving it. I will always remember the feeling of joy and amazement as the whaleshark passed at less than 2 m from me. If you follow tge rules you will not disturb them or interfere. But sadly i saw some people which did not do so on the boat next to ours. It is true the whalesharks seem quite domesticated as they follow the fisherman boat along the bay.
You get on a boat and stop less than 100m from shore along oyher boats. You spend 30 min or so there enjoying the whaleshark experience. It is very safe.
Please follow the rules and just enjoy these moments
