Control what events require an RSVP
If you don't need a head count for every event over the course of your wedding, you can disable the need for guests to RSVP to certain events within your Editor. First, you will want to go to your Party/Schedule page and then go through the Schedule Events and click on the pencil icon next to the event you want to remove the need for an RSVP.
Then, you can scroll to the bottom of that event and toggle to disable "Require RSVP" and remember to click "Save Event".
Once this is done, your guests will not see the option to RSVP for this event within the RSVP form.
