With the tour booking web widget, you have the ability to provide times for prospective customers to view your organization prior to signing up. Using the booking window, you can set parameters around how far in advance and how close to the start time someone can book a tour.
To add or update your booking window, head to Settings > Web widgets > Tour bookings. At the bottom of this page, you'll be able to make changes to your booking window. You can specify your desired parameters by the minute, hour, or day.
