Question for SF Marine World passholders

Hey, I have a question for those who have had their Six Flags season passes processed at Marine World in Vallejo. Could someone let me know which coupons for free and discounted friends are in the coupon book, and which days they're valid for if there's a date restraint? I haven't gone yet this season so I still have my voucher, and I'm going with a friend next week who doesn't have a pass, so I wanted to get her some kind of discount. Thanks to anyone who can help me!

Ahh, my book is sitting on my desk back home in SF. I'll let you know by Monday if you can wait....

You can bring a friend free till June 30. In July 1-3 you can bring a friend for 1/2 off. All September is 15$ off. And there is one more bring a friend free in September to Oct. 4. Hope that helps!
