Each adventure activity is separate from the stay. Free activities include hiking and biking (if you bring your own bike). Activities like rafting, ziplining, waterpark and Aerial park etc are all extra purchase options. There website will have more info on what's available. It's an amazingly fun place and highly recommend.
I agree with Erica. My family had a blast. My son and I also did outdoor rock climbing, which is also an extra.
