Guests Allowed refers to additional people that creators are allowed to bring when claiming your in-person Node. This generally applies to restaurants/venues that involve an in-person experience where your complimentary offer will also be extended to the additional guest(s).
For example, if a restaurant allows 1 guest per creator, each creator that claims your Node will be able to bring 1 additional person who will also be able to receive your offer.
We generally recommend allowing creators to bring at least 1 guest as it makes your offer more enticing and allows for a better spread of items to be captured within your content.
