We enjoyed it but it is regimented. They take on you tours, on pre-defined trails, more or less in order. Also, it's only open on weekends and they ban (actually, just discourage, you carrying lights).
In their defense, they get a lot of warm-water beginners. Also, I think keeping it dim and have a progression of paths just keeps it more interesting.
So, if you are in the area and cost is OK for you, you can enjoy it. If you are planning a trip, however, I'd recommend first, guided cavern diving near Playa del Carmen. https://www.facebook.com/media/set/?set ... 0f2ebed49d
