Do we need a second shooter for 100 guests?

For 100 guests at a single venue with no transit, a second shooter is a "nice to have" not a "need to have." The math:

What a second shooter actually buys you:

• The groom getting ready while the lead is with the bride
• Coverage of the aisle from the back while the lead is shooting reactions from the front
• A different angle on the first dance
• Safety net if a card fails or a body breaks

For 100 people, one experienced lead can cover the day end to end. Where it gets hard: getting-ready coverage if the parties are at separate locations, and the aisle moment where you only get one angle.

If your $800 has to flex, here's where it lands harder than a second shooter:

• A longer total coverage window (8h → 10h)
• A higher tier package with prints/album
• A dedicated videographer if you don't have one

If you have getting ready at two different locations, or you really care about the aisle reaction shot from a specific angle, the $800 is well spent. If neither, you're buying redundancy more than coverage.
