You can set up sub-events that span multiple calendar days, like a three-day workshop inside your week-long reunion. Your guests see the full date range on the booking page and across their personal itinerary.
What you can do:
Mark a sub-event as a single-day event or a multi-day event when creating or editing it.
Pick a start date and end date for a multi-day sub-event.
Show guests the full span of the sub-event on both the booking page and the itinerary.
How to access this:
This is available in your account. Open any event admin, go to Settings → Sub-events and schedule, and you'll find the Sub-event type field on the sub-event form.
