You need no coupon to go online and purchase tickets for $29.99- everyone pays kids price.
Schnucks offers discount tickets too.
If you have purchased or know someone who has purchased an Entertainment Coupon Book there is a Buy one Get one Free in it.
My employer recieved half off any day coupons earlier this year and I took one hoping to take my son this year. We are planning our trip for Aug 9th. If you would like to try it I can scan and email my coupon and you can try and color print it and use at general admission gate......
