If you have a large area and want to auto-confirm multiple groups/bookings into that area, you need to set this up in Settings, go to:
Venues > Select the Venue
Tables/Areas section on the left-hand side
Alongside the relevant table/area, tick the "Multiple groups" box
You can then add a ‘multi-group buffer’. This acts as a gap between the bookings and separates the different groups by a space of 1, 2, 3 or so places. This works off the 'max (seated) capacity' so, in the example below, two groups of 3 people could be assigned to Table 1 but not two groups of 4
Make sure to SAVE the page
