How to stop sweating so much?!?

I'm going to an amusement park tomorrow with my boyfriend, his friend, and his girlfriend. It's summer, so it's going to be HOT! I hate sweating and smelling bad... I know that "if someones sweating, chances are, someone else is too." I understand that, but I really hate sweating. It disgusts me, really. I'm a golfer, so I'm out in the heat all the time. But I don't think that's going to help my case at all! So any ideas on how to not smell (lol) and not sweat as much?! Thanks!!!
