How can I convince this girl to...(you know) on vacation?

I'm 16 and she is 15. she looks like she is ******* 18 she is so hot! so what should I do to sweep her off her feet and get her to ****. I'm going to Hawaii kona. and we are staying in the same house. what kind of things can I do, like maybe a "morning run" just the 2 of us to an amazing sight. then convince her to go swimming... help me out! thanks. and I met her past week and she was super Horney and obiously had a thing for me.
