I just went this weekend. its 10-20 depending on the parking lot. An it's more on the weekend vs weekday. So 25 to 30 on weekend.
$10 a day in the lot next to the aquarium. That was as of August 2019.
Parking varies by day. I think the most we paid was $20 and that was on a holiday. It's usually $5 to $10 for half a day.
Honestly, I went so long ago but I parked across the street at this parking lot that had gravel floors and I believe it was in the range of $5-$20 for the entire day.
