don't worry in the aquarium it is easier to find parking easier and cheaper even without paying
Yes they have a parking lot between the shedd aquarium and the planetarium that you can park in and it's $25 for how ever long you are there
I parked a little ways away at a parking garage and just walked their.
There is parking along both sides of the road to the right of the aquarium. Find a spot and walk up to the "pay by plate" machine. Follow prompts and make sure to take your ticket with you. Defiantly the cheapest way to park. Lots get full quick and they can be a little expensive for not much time.
I didn't see parking onsite .I parked near skydeck and from there took Uber .
