Question about group sales

I'm going on May 15 with a school club. I have to buy a ticket even though I have a season pass so we can get the group rate. The tickets are $25 apiece, so I was wondering if I would be able to buy some for some other friends who won't be there. Can you buy extra tickets, or do they check to see that you're only buying one for each person in your group? Either way, I'll make at least one friend happy with a $25 ticket.
