Got CWV Invitation

I just got an invitation to CVW a couple of weeks ago, and immediately accepted. I'm super excited! For anyone that has gotten a drag a couple of times or anyone who's been before, what is it like? Anything I should do beforehand? What's the schedule like? I don't even know how they found me lol, I only applied for NASS, but I'm glad I didn't have to go through the trouble of asking a BGO
