Accessibility is an issue. No access from exit to parking lot for wheelchairs and strollers. You have to leave the precinct and get back in around the block.

The first area was very crowded, making it nearly impossible to get around on a stroller.

A/C barely works, making it an uncomfortable experience in the SP summer heat in January.

Although it was not at full capacity, the food court felt crammed, with wooden tables and seat taking blocking the aisle. That meant that visitors had to push seats to make their way to the exit.

Variety of fish and marine mammals is interesting, but the crowd makes it impossible to take in the experience to the fullest. Information on species could be more widely and easily available. The premises becomes more spacious, though, once you get to the animals of the world section. However, all animals looked exhausted with the 35C heat at noon.

The steep price tag of R$60 for a child of 2 and R$90 for an adult makes it an overpriced attraction for Brazilian standards. The R$ 35 reais parking was bare, having no shelter. Food and souvenirs are similarly overpriced.

I would suggest arriving early on a Monday so as to avoid the crowds and enjoy the promotional price.
