Parking is 25 and we had to pay 39 per adult (non-chicago resident prices) it included a water show the the dolphins and sea lion.
If I remember correctly it was around 35.00 per person and parking is 25.00. There is metered street parking if you're lucky enough to find it but on the weekend it's doubtful. Also if there's any events going on in the area they close off the street parking and raise the lot parking to 50.00.
We paid $39 per adult, free baby. We were lucky enough to find metered parking on the street leading out to the planetarium, so we paid $6 for 3 hours.
