Need serious logistical dating advice?

Okay I am at this big campground that my family goes to. Me and this girl have had a thing. It has only been a week really but the feelings are definitely mutual. I tried to subtly ask her out tonight and she said yes and she would be up for doing something but her family is staying at camp for three more weeks and then she has another week at another camp. We both live near each other but I cant wait 4 weeks at all because we both go off to school in the fall and wont see each other much. What should I do. The camp is like an hour away.
