I visited on a Wednesday afternoon at about 2pm and it was completely dead. There were maybe only 3 people working there and it took a few minutes just to pay the cover because no one was working the front desk. You had to pay a big cover and there wasn't much activity happening. Then to go to the back you had to buy a wrist band which really wasn't worth it either. I would recommend going later in the evening where I assume it would be more crowded with people.
