Horribly late to this due to just a lot going on today, but here we go!
Brigitte definitely went because she's made a lot of friends and enjoys anything party-adjacent and socializing and while she is totally clueless about relationships, she is totally on board with love is love. I assume she'll meet up with Scott and Stiles for a bit after their conversation the other day but most likely would drift towards people she knows best, like Atreus, Torunn, Connor, etc.
Korra would've gone for a bit but would have been keenly feeling Asami's absence after a bit and would've likely spent the rest of it hanging out in the forest with Naga, trying to find spirits to talk to.
Kratos did not go, though he probably had a few affectionately grumbly comments about Atreus' look.
