2 admissions and 4 attraction tickets. Parking is $14, I saw Brookfield zoo on Groupon if you needed to buy additional tickets.
I have 4 Day Out With Thomas train show tickets for Sunday, July 21 in Union, IL. The tickets will get you on the 20 train, but you can go to the event for as long as you like. I purchased the tickets for family members who ended up having to cut their visit short and they are non-refundable. I originally paid $84 for them. NO REASONABLE OFFER REFUSED!
