You cannot convince me that Percy did not, PERSONALLY, ask Hestia to attend his wedding as a patron, instead of that b*tchy-hag known as Hera.
Like he approaches her at camp, everyone else watching behind him all confused, while he asks her verbally to attend his wedding, with a basket of gifts and an envelope invitation to his wedding to sit in the front row with the parents. And Hera isn’t even allowed on the wedding’s premises.
(Hades and Persephone are also invited, they bring Cerebrus)
Hazel is the flower girl and Nico is the ring bearer.
