I'm planning on going to Furpocalypse

I'm scared that because I don't have a fursuit I'll probably get denied despite the fact I have a ticket. And I'm trying to socialize, make some new friends, and especially learn how to draw. I know the basics: stay hydrated, avoid room parties, seek for any events that catch your eye, have fun and don't be creepy, I got all of them. I'm still nervous. What are some other things that I need to do?
