"I will come to their wedding."
Translation:Tôi sẽ đến đám cưới của họ.
I agree that it sounds natural to use "come". As far as events go, I use "come" as though I'm saying "attend" versus saying it as "go" to mean I will be transporting/be in the act of moving my body towards the wedding. Lol, idk if that makes any sense.. but that's what naturally comes out of my mouth when I'm saying I plan to be there
