Hairstyle for special trip?

Tomorrow me and 3 friends are going to Cedar Point for the day. I have my outfit picked out (I'm wearing a tube-top or whatever you call it a shirt with no sleeves, and a ruffle skirt. Both items are navy blue). I don't know what I should do with my hair! I have medium length (5 inches below my chin) and it's dark chocolate brown and it's thickkkk and curly/wavy/frizzy! What should I do as a hairstyle? Remember, I'm going to be on rides all day. THANK YOU ALOTT !!
