Thereare three methods you can use to allow clients to doublebook for the same appointment time through your online scheduler: Multiple spots for the same service; using multiple classes; or using multiple calendars.
This will allow for clients to book the class service like a standard one-on-one appointment at any time, as well as allow you to add it to your calendar on specific dates & times to make it available.
Once your services are set, you can add the empty classes side-by-side on your calendar (see Method 1 here) to make multiple services available for the same appointment time. You can also set repeating classes to easily make these available at each appointment time each day.
