Ask questions, meet dancers, and be part of the conversation.
Sometimes I think this is deliberate. They know their partner is used to their funk and everyone in the on deck area not so much. The funk might take all the oxygen out of their competition's lungs to give them that slight edge they need.I have learned that more people need to clean their costumes and put way more deodorant on. You don't realize how bad it can get until you are standing where judges are for the entire event. So gross.
I SO can relate to your post about being mentally and physically unprepared- my first comp with current pro was all of that- it was bad- and worse- I wasn't expecting that- plus I didn't want him to see me in that vulnerable spot- fast forward- and now I am better, stronger, less vulnerable- but I feel for those that are in that spot, because it can happen to any of us at any timeI learned that there is a level of feeling mentally and physically unprepared that means that I really should not step out on the competition floor! I also learned that even if you have been dancing, if you have been dancing poorly, you don't necessary have the muscles to dance well. All in all, it was pretty awful. At one point I asked pro how many heats until our next set. The answer was 12, so I said, "Good. I need to go have a short break down." When I got back, he tried to say encouraging things, and I had to tell him to stop talking because I couldn't afford to cry...given the eye makeup and no time to fix it and all. The primary issue is a bunch of non-dance related things going on that are resulting in my being exhausted, stressed, not taking care of myself etc. I just (ha!) need to fix all of that. Honestly, if I hadn't tried, I wouldn't have known that I had hit my limit.
The good part of the weekend was watching the New Guys. One did very well in the pro competitions. His partner works for another studio, so it gave us an extra set of students to watch and cheer for during the competition. The other one did very well with his pro-am students. Everything you want to see: supportive, engaged, they danced well, he managed the "look good without overwhelming your students" thing, which is not always easy. Very, very nice. Another one of his students came to watch part of the competition to get a feel for it and will likely compete sometime this year. I had coffee with some of them this morning and one of them said something very astute about the studio and the owners, "I don't know exactly what they have done to create what we have at the studio, but I am positive that it is not just accidental or a coincidence."

I find it stressful negotiating the semi-social situations at comps. I like it when the pros announce, "Everybody is going to have lunch together. Come join us." or "I am going upstairs for a while. Do you need anything before I go?" (i.e. I am off duty, I need a break from all of you for a while, don't interrupt me unless the hotel is on fire--and actually, even then you can assume somebody else will let me know.) My first pro, having seen the awkwardness that students go through, even explained to me what to expect before our first comp together.
