Yep, people will get the idea. I know this because I went in January as a solo traveler and was seated with two other solo travelers. I'm an outgoing introvert (that's a thing!), and the woman at my table was very friendly and we chatted a lot before the show and after and had a lot in common. The man at our table was the opposite of that. I said hello to him when I sat down and he politely said hello back and then NOTHING ELSE the entire time. Just drank his hot chocolate, ate his desserts and watched the show without engaging. Which is totally fine! Neither I or the other person at the table were going to make someone engage with us who had no interest. We're there for the show, not to make friends, so it's easy to decide what level of interaction you want to have with strangers.
