Would you like for there to be sparks between you and this girl?
If so, plan an activity that makes your heart race, your adrenaline pump, or that makes you laugh.
If you get the "feel-good" chemicals pumping, it will be easy for her to associate excitement, fun, and joy with being with
you.
Also, in the case that you want to create a bonding vibe, I would disagree about asking her what she wants to do. Better to boldly plan and lead her into a fun adventure -- and have a back-up plan in case she's allergic to your first idea.
