I have a full day option that they can add via a'la carte to any package, which generally covers 6 hours. Don't let a South Asian wedding intimidate you. Majority of the time, they don't know what they need, and think they need full 3 days... when it's really 2-3 hours of something important (minus the main wedding day). Figure out exactly what they need photographed, and then quote them accordingly. If you're going to charge your full rate for 3 days worth of coverage, there's a pretty good chance you won't get that gig. Regardless of how you charge, be prepared for a lot more work vs your traditional wedding.
