Guests have three questions: where, when, and what do I wear. Everything else is decoration.
List the roka, tilak, haldi, mehndi, sangeet, the ceremony itself and the reception, each with its own date, start time and venue. Guests invited to two of six need to see which two.
A muhurat at 7:10pm means guests should arrive by 6:30. Say so. It is the single most useful line on the page.
Paste a Google Maps link for each venue. "Behind the old petrol pump" is how people actually navigate, so add the landmark too.
Haldi ruins clothes. People want to be told.
Hotel names, the block booking code, and roughly what it costs. This removes most of the phone calls.
A single yes or no for the whole wedding is useless to whoever is ordering food.
Not yours. A cousin who has agreed to field questions.
