I have these coke cans that can let u pay kids price at Six Flags. Can my friends use them?

Im planning to go to Six Flags on monday. I haven't been there in like 2 years. Its gotten expensive. Regular admission price is 46.99!! Luckily my Dad bought this coke zero pack that has a six flags coupon on the can. It says "Everyone pays kids price"( Thru 9/25/2011) How does this coke thing work? If my friends and I have the cans we will all get to pay kids price? Kids price is 36.99.
