I'm an Alpha Xi at UCF and the main thing to remember that what you feel is COMPLETELY normal. It's weird coming into an organization where you don't know any one and the older members all seem to have their own "groups." It takes a while to get to know everyone but don't give up! Hang with it and you will never regret it. PM me if you ever need advice or questions about Greek Life in general at UCF. I can't help you with the ADPi stuff but I can definitely let you know about the campus and Greek Park.
