Maximum Number of Guests
If you have an open RSVP form without an exclusive guest list, this option allows you to limit the maximum number of guests a household can RSVP per submission. 10 is the default maximum number of guests in a household. You can decrease this limit.
Exclusive Guest List
If a guest inputs a name that is not on your guest list, then they will not be allowed to RSVP. You can enable this option if you only want people from your guest list to RSVP. Otherwise, if you remove this option, guests not on your guest list can RSVP.
