"hanging out" with this girl

ok, this girl and I are going to hangout on saturday, I've had class with her before in HS, but we're both in college now and we've been exchanging messages on facebook, she found me on facebook and messaged me first, and we've been messaging for about half a month now, she says she misses me, and all that stuff.

I asked her to hang out with her, since she messaged me with "i misss youu" a couple times already so why not? right?

now my problem is, I'm not really experienced in this, I've had a crush on her since I've met her, I'm not sure if she's really interested in me, or if she wants to hang out as "JUST FRIENDS"
what should we do on saturday? shopping at the mall? movie? minigolfing? haunted mansion attraction?

hopefully some girls and guys can help me with this.

thanks,
Johnny

She misses you meaning she wants you.

About the date? I dunno. I'm not into dating "usually".
Before I had my ex, when we had a date, we usually went to the beach, brought food and talk about the two of you, the past experiences. What I like about him is he know how to handle things. When it comes to conversation, he always inject jokes so that I wouldn't be bored. And also in that conversation, you know a little about him.
