Girl invited me to stay with her on holiday... Should I go?

Recently started seeing this girl i've known for years and we've been seeing eachother when we can as i'm at uni still and she works. We haven't really spoke about relationship talk as we seem to just enjoy eachothers company, we do fancy eachother though. Tonight she asked if i want to stay at her dad's place abroad with her... Does this mean she's very interested or can she still see us as being casual? Also is there a way of getting it out of her what she thinks we are? bit of fun or something else? any help would be great!
