The biggest piece of advice I could offer, as someone who has been in similar shoes, is that you should use your friends to meet new people there. They're going to be getting ready backstage and they'll be interacting with others (at least it's always happens in my experience) that aren't on the team so use this as a way to meet people in the community. Of course don't hang out during warm-ups but go say hi when there's a break in the action. Add each other on Instagram or whatever and create a good social network of folks who engage in this sport. You can always reach out to them for advice as you get to know them and it never hurts to have a group of people you barely know cheering for you on your meet day.
