Offering multiple durations
This feature allows a single event type to have multiple time options (for example: 15, 20, and 60 minutes). The guest picks the length that suits them best before choosing a time slot.Why use multiple durations?
- Cleaner Profile: Keep your booking page simple by grouping different time options under one event.
- Guest Flexibility: It gives the booker the power to choose exactly how much of your time they need.
