I'm scared to travel to Prayagraj and Varanasi in April with old parents.

So I've planned to visit Prayagraj and Varanasi in the month of April with my parents and old Aunt from Mumbai. My Aunt is 70 plus. But I'm shit scared looking at the videos people throwing stones and breaking windows of trains. Will the crowd get better till April? i know the crowd is because of Kumbh, but still maybe I'm too irrational to be scared. Also what are Dos and Don'ts for travelling these two cities?
