I had a blast at COL, even though it was a little tiring to meet so many people and do the shotgun-style socializing
I thought it was fun, and you have to go with it and be willing to do silly team-building activities for a couple of hours. I definitely recommend going, because that's where you'll meet your PRN group and be able to start finding people in your class to click with. My group completely hit it off and had a great time, and we still do stuff together. You'll hear from other people who thought it was dorky, but don't take yourself too seriously and you'll make more friends that way
I think the main objective of being there is to meet your classmates, and a lot of Baylorians put a lot of effort into making y'all feel welcome and trying to make sure you have a good time.
