Do couples need to make prior arrangements for Veni Daan in Prayagraj?

Yes, it is highly recommended to make prior arrangements. This includes booking a knowledgeable Pandit familiar with the specific traditions (especially if the couple is from South India or Maharashtra), arranging for Pooja Samagri (unless included in a package), and booking a boat for the Sangam. During peak times like Kumbh Mela, advance booking is essential.
