We've been there twice (we have family there). The first time they were 4 & 2. The second time they were 9 and almost 7. My oldest was the one that was most freaked out by them and he is mostly ok now. He will still not choose to go anywhere close to them or interact with them (a wave or eye contact) but he no longer freaks out when they walk down the stadium steps when we're 10 seats in from the stairs like he used to. My youngest kind of follows his lead so now that he's better, she is as well.
Good luck!
